When you look for a new ball you need to look at what type of hook you want.
Hey! Welcome to Bowling Community, T!
I like TenPin's answer too, but I think you'll probably be able to make use of it later after you have more experience. (regarding revs - a typical league bowler is 200-300, a pro 350-450).
Since you're a 150 bowler like me, I would suggest a ball that arcs all the way down the lane rather than one that skids on the oil and then flips in a sharp snapping hook at the break point. I have several of the former and two of the latter.
I have no idea about the type of ball, so can't respond to your question in that regard. However, an important consideration is the drilling, which can be done at least 2 ways -
1 - control, with flare so that the ball curves all the way down the lane with a mild hook at the back end
2 - length, sot that the ball goes more straight on the oil with more hook at the breakpoint.
I would suggest that you will want #1, especially if you always bowl on THS (typical house shot) oil conditions (what most leagues use) and not sport conditions (like PBA experience or Sport bowling).
I love my Danger Zone, with its skid-
Flip, but it only gives me 1-2 strikes per game, while my
Brunswick Monster with its long curve all the way down the lane consistently gives me 4-7 strikes.
BTW there's a thread on drilling patterns that might be of interest. I haven't read it yet....
One more point - Only drill one ball. Use it, and determine if the grip is right before you drill a second ball. There are recent threads on span and grip too....
