Weird ball weight experience
« on: January 02, 2010, 12:27:27 PM »
Okay, I made the move back to 16lbs about 2 years ago, and overall it's been a good move for me but I've been having wrist problems do to participation in other sports and I thought about moving back down to 15 so that I can continue to make changes with hand position instead of having to make a ball change.

Has anyone else experienced the opposite of what would seem to be the norm when making the change down? I average between 16.8 and 17.5 with 16lbs whereas with 15lbs my ball speed drops to the 15.2 to 15.8 range. With comparably drilled balls (Same make, layout, pattern) the 16lb hooks more for me, but only by about 3 boards.

I'm probably still going to make the move back down, but I was curious why I might be doing this when I bowl. I know the general consensus is that my ball speed and hook should have both gone up with 15lbs.

Thanks

Where is the ball speed being measured?  If it's measured just before the pins you need to take into consideration that a 15# ball loses momentum faster than a 16# ball.

Ball speed will only increase if you're physically moving the ball faster in your approach.  If your tempo has pretty much remained unchanged, so will your ball speed.

I don't know where it is being measured, because it's just your standard speed read out on the score machine. As far as tempo, I made sure that everything stayed the same in terms of style and tempo.

I found it odd, because everything I've ever seen the opposite should have happened in terms of speed and hook.

If what your saying is true though that might explain it, but I just found the whole experience odd.

Basic physics say that balls of different weights will fall at the same speed.  However, it might be possible that you do not offer as much resistance to the 16 lb ball as you do with a 15 lb ball because of the greater weight.  If that is the case, the 16 lb ball will "fall" through your swing with less resistance (thus more speed), which should result in a faster overall ball speed.

See, that made more sense to me as the reason for the extra speed. I can feel the 16lb ball better in my swing, and it allows me to not fight the ball. I think what happens with the 15lb ball is sometimes I can't feel it in my backswing and so I slow it down to find where it's at.

It wouldn't be the first conundrum I've experienced with my equipment. My Spit Fire owns my Cell and Gravity Shift on most shots in terms of overall hook. Still can't figure that one out, unless Symetrical balls just move better for me than the Asymetrical balls.

Motogp69,

I found the same thing with 16s vs 15s. For some reason I was able to get a better, cleaner release with 16s and was capable of throwing them faster than 15s. I also had to to return to 15s. So now that aspect was not involved in the equation any longer. Oddly, after 9 months of being back with 15s, 16s feel very heavy now.

Yeah, it's just that I do brazilian jiu jitsu tournaments, and the locks and  holds make my joints entirely to flexible for 16lbs.

If you get more revs on the 15 lb ball, slower speed on most of the scoring systems will result.  They measure at about 50 ft down the lane, Qubica is one example.  More revs creates more friction causing the ball to slow down more, especially when it hits the end of the pattern.  --  JohnP
