Expected Reaction?
« on: March 17, 2010, 01:03:39 AM »
I'm hoping someone can help me, because I want to know if I should get a new ball...

I received a Mission X-OUT from a friend (my first, ball just started bowling 2 months ago).  Anyway, I took it to the Pro Shop and had the Pro there drill it.  She said she wasn't sure how it would react and explained to me why it was an X-OUT but I didn't really understand.  I think it has something to do with the PIN, CG, MB (aren't they all suppose to be in a straight line?).  One of the marks is way off...  I drew this in paint since I haven't had time to take an image hoping someone could help.

The red mark is the pin, the green mark is the little hand symbol (CG?), and the orange dot is the other mark (MB?).  Of course the black dots are my holes (finger tipped).

So my question is, how should I expect this ball to roll?  I have low revs, and an experience bowling I bowl with said he would classify me as a stroker type.

1. It is not unusual for the pin/CG/MB not to be inline. Some people and some drillers even prefer that. It is unusual for the CG to be 2" or more from the pin-MB line.

2. The relationship of the 3 points HELP to determine the possibilities of the placement of the pin and the MB with respect to your PAP and the reaction you'd like to get from the ball. The actual position of the CG is unimportant to the ball's reaction.

3. Where the CG does come into play is 2 places:
a) How the static weights can be made legal. If the CG is not within certain parameters of the center of the grip, a weight hole may be necessary to make the ball legal.
b) The weight hole can have an extremely important role in the ball's reaction. So when the CG is way off line, that can prevent the driller from putting the weight hole where it is necessary or useful, depending on where he has determined the pn and the MB must be to get the desired reaction from this ball for you.

So it's not what reaction will these points (pin, CG, MB) provide. It's where can they be placed to get the reaction you want.

Usually when the CG is so far away from the pin-MB line, they will call this a "Pro CG" ball.

your pro shop operator should've weighed it before drilling, and then they would've known what was what

but as said many times before

Ok, I think this helps a little, but I'm still confused.  Is the hand symbol on the mission the CG or MB?  It's in the center of my grip so I thought it was CG.  

Like I said, I'm clueless about these, even after reading this:

http://www.bowlingfans.com/jeff/ballreactionbasics.html

I'm guessing you can't tell me what the ball will do based on my diagram without knowing my PAP, etc...  I'm so frustrated... This is suppose to be a heaving hooking ball from what I can tell, but this ball doesn't hook much IMO and I have no idea if it's my release or the ball, or the way the ball is drilled.  Which is why I asked here.

If it was easy for me to go ask the Pro more info, I would, but I work a lot, she's closed when I'm available, etc... Having a 11mo old daughter doesn't help matters...

I just recently drilled up a original Ebonite One x-out very similar to this and it rolls great.

Many people are scared of bowling balls like this sometimes and shouldn't be.

As long as she has a general idea of how you throw the ball when she laid it out you should be ok.

Judging by the pin position I would say the ball should roll very aggressive. I have drilled many balls similar to this with the MB out near my positive axis point and the pin close to the fingers with great results. All where great aggressive bowling balls.


Just don't do like some people and throw the ball less then a game and say it doesn't work right.

No, no.  I've thrown this ball since my 3rd week of league, so maybe 5 weeks now, and other than that it probably has around 20 practice games on it.

I haven't had time to get a lesson yet, which I'm really wanting to do, but I feel like I don't get much reaction out of the ball.  I'm not sure if its my release, the ball, or something else (like just being a new bowling and being inconsistent).

Anyway, I really appreciate the informative responses.

Honestly, IMHO (and from personal experience and insight), if you are a beginner a strong MB ball like the Mission or any other high end asymmetrical piece is potentially a BAD choice.
This kind of ball calls for a proper and stable game/release, and they can be very touchy concerning the drilling and setup because through the core's construction. They tend to follow a more specific reaction than "normal" balls, and generally offer less room for error and versatility concerning lane conditions.

Using a blem or X-out ball does not help either. Sure these can be drilled, and sometimes are a good choice for a specific reaction. But I would not wonder if you get a goofy reaction out of it...

IMHO, wrong ball at the wrong time - even if it was cheap or even free. A simple, mid-prized piece would IMHO have been more sensible - good luck, though!

dizzyfugu, can't disagree, however the ball was free, and so it's what I have to use for now but I think I'm going to try to get another mid-range non X-OUT ball...

Ebonite's standard marking for cg location is a series of concentric circles.  I've only drilled a couple of Missions, but I don't remember an unusual cg marking.  Maybe they mark cg's on their X-outs with a "hand".  --  JohnP

it looks to me like the ball is drilled to roll early. could be if you have a slow ball speed or not too many revs, that the ball is rolling too early which will give it the appearance of a dead ball.

You are right, it is a series of circles... It also turns out my illustration isn''''t as good as I thought (done from memory).  I took pictures:

In this first pictures you can see the pin and CG are nearly next to each other if you draw a line from the pin to MB (the mark on the bottom left of the ball)

Second photo just shows more top down view of the drill with pin and CG.  The MB would be somewhere on the bottom right.

Sounds like a traditional Columbia CG marking? That used to look like a hand on top of a bowling ball?

Without knowing your pap, in general, this ball should roll immediately off your hand and flare a lot. Unless you have huge speed/and or large degree of tilt, the ball may appear to not hook. We usually look for hook downlane, so a ball that goes into forward roll immediately off our hand does not seem to "hook". Your driller did a great job, this is about all one could do with this ball!

pooh, thank you very much for the information.  So would the best 'throw' or line to use with this ball if I don't have a lot of revs by to throw the twig at a low speed?

I trust my driller a lot, she's a former pro and knows her stuff...

You say speed would make the ball appear to hook, do you mean revs? Or perhaps both?

Did your driller confirm the cg location with her dodo scale, and what were the final static weights?  I agree that if the cg location was correct she did about all she could with it.  What is the layout, especially pin to PAP distance?  If it's rolling too early some polish might help it, and depending on the static weights a properly located balance hole might also help it.  --  JohnP
