i have a no mercy with the #4 drilling but it seems to be really choppy like one shot it wont finish next shot hitting same mark will hook 2 much, my speed is fairly consistent so is my release but the ball reacts different all the time, im thinking about getting it redrilled with the #1 drilling or getting it polished

any one have any ideas as to if its worth changing the surface before redrilling but from the feel of the ball i think the drilling is shot!

anyone else had these problems with the no mercy with other drillings apart from the #1 ?

thanks in advance

i haD MINE redrilled and it really made no difference in the ball i wouldnt waste the money do some surface changes maybe so to lower grit. I had the same problem with mine friday night .min is at 1000 and it was so over under it was rediculous. imho i would if the surface changes dont help just go with something else ,its not that great of a ball unless u have dry somewhere or you can play an extremely tight line. Very little room for error with this ball.It has been my experoence that redrilling just doesnt change the balls characteristics enough to make it worth it. Epic battle ,wmb,no mercy,all still pretty much the same. the first two i had drilled 3 times apiece.

drw02,

    I would definitely try it at 2000 but no polish to help with over and under. Should smooth out your reaction off the dry and help recover when tugged in the oil. Just make sure you are lined up in the oil or the edge of the oil line. If you are right of the oil line and swinging dry to drier, the ball will burn up energy and still appear to hook but hit flat or stop on the end. I feel most success with this ball is afew boards left with feet and target than your typical house shot line. If I leave a flat ten, normally I might think move feet right to improve pocket hit due to carrydown, when actually the correct move is feet and eyes left to keep ball in oil longer to prevent early read, roll and quit. It can be a tough thing to see sometimes. But overall, 2000 should even out the reaction. Al

To me it sounds like a combination of a spotty oil pattern(over/under?) and or  inconsistant release.  

Next, before you ever plug and re-drill a ball, try a cover change.  I really like my NM at 2000 grit abralon.

Now you ask if you should polish the ball or re-drill it with the #1 layout?  That's kind of two different directions.  Polishing the NM will make it go really long and have less over all hook.  The #1 layout will make it stronger and hook more.

Now someone said that this ball needs some dry boards to react.  Every bowling ball made needs dry boards to react.

Consistancy!  The NM has one of the most consistant reactions i've ever seen in a bowling ball.  It doesn't wiggle in the mid-lane.  It doesn't squirt at the break point.  It doesn't slide in carrydown.  The only fault I have found in this ball is when the lanes are too dry.  If the lanes are too dry it will burn up and hit a little weak.  If the lanes are too dry it will be hard to control because of it's strength.

I know some have had problems with this ball.  I know of two guys that had problems with there NM.  The problem was that it didn't hook a lot.  Both of there balls were drilled wrong.  The pin was not based on there personal pap.

I will say this again.  Take the cover down in grit and try it out.  Take it down to 2000 and try it.  Then 1000 and try it.  See how this works for you.  You may also want to try it out on a few different lane conditions.

The layout you have makes the ball very smooth on the backend. Plus if that ball isn't thrown on the right condition it can be tough. I don't know what type of player you are so that's hard to make a decision what is exactly wrong
besides guessing on the pattern you were bowling on. Maybe if you can describe in detail how you throw the ball.what type of rotation, track high or low, and etc.
