Well guys im back in the game for the first time since 2006, where I had a bit of an incident at work that broke 2 bones in my hand with tendon and nerve damage. ( pic below ) And am going to jump back on leagues this fall  and thought I would ask for a little advice from you guys..

 The ball I throw now is a Zone black ice, which is nice, but im thinking of just polishing it up and using it for a light / medium oil ball, So I just dont want to but a new version of what I already have already, So im looking for something aggressive , but controlled..  The ones I have been looking at Have been pretty hi end balls with a heavy backend ( from what Ive been told ) such as the C system 3.5, Mission, Jigsaw corner, Evil Siege, Invasion etc , and am wondering if thats gonna be to much ball for me.. The Zone Im throwing now is 16 lbs, and Im getting it down around 16 mph, with a "guesstimated" 350 Rev..

Im standing pretty far to the left and try to have more of a heavy curve than a heavy hook on the backside, if that helps any.. I know its hard for you guys to judge, but the local proshop in town has NOT drilled alot of these balls, so I cant get alot of info on them  as far as how they react or how they should be drilled..  Ill let you know what kind of oil patterns are used when I get a chance to know myself

Oh and also I will be dropping to a 15# possibly even a 14, Unless thats too much of a drop..

All the balls you've mentioned are pretty strong (as in, need lots of oil on the lane for them to work). I'd suggest going with something weaker, look for something in the mid-range of what most companies have right now and that should be ok. 15-14 should be fine, just take care not to muscle the ball too much which can be a temptation with the lighter weight
