I have had nothing but problems with my NM.  It is to aggressive. I have slower speeds (14-15mph) and the ball flares way to much. I don't have a lot of hand or revs on the ball. I have it drilled with the #1 layout.  Should I try adding some polish to it, to make it go longer or try something different.  I am a lefty and consider myself a stroker.  What should I do to make this ball more usable for me?  Thank you. Most of the lanes I bowl on are medium oil.  I thought this would be perfect, because most of the other balls I use or have tried, Total NV, radical inferno, scorchin inferno, sd-73, angular one, etc. have not reacted very well, they just seem to skid and then don't hook until it is to late.  When I first got the Total Nv it worked great but now it doesnt.  Please give me some suggestions.  Thank you.
