I'm 18 now, and about 5 years ago i started growing, and lost all coordination i ever had..  now that i'm done growing, i've decided to come back to bowling... problem is...  

I had bought a 13 lb Gyro Pro, Reactive ball, very little (if any) weighting on the inside, and so now i'm starting to notice i come in light an awful lot.  I didn't take very good care of the ball when i had it, and as such, the cover is shot, i barely get 4 or 5 boards out of it, so I'm in the market for a new ball.  Right now I don't have a whole lot to spend on 3 different balls for dry, med and heavy oil, so i'm looking for something that i can throw in pretty much any condition, that's going to get me a bit more push through the pins.  

I wouldn't feel comfortable going into a pro shop and asking to be watched because i'll basically be developing my game around whatever ball i choose.  

I'll probably keep my Gyro as a spare ball, because if i put any sort of speed on it, it barely reacts at all.  

Any suggestions, or good questions to ask the pro shop guys?
