My bowling buddy has a collection of Storm Balls he's selling because he is having a baby and can't bowl as many nights a week now.  

I am right handed, 5'9", and weigh 220 lbs.  My shot is mostly down and in with the 7-8 board the most that I usually work out to and the most I move left is the dot to the right of the middle on the approach.  

I'm interested in buying 3 of the balls to replace my old equipment.  

Here is what he has:

Hyroad
Second Dimension
Reign
Paradigm
Fast
Furious

What should I get?  I throw a blue Hammer for my spare, so I'm looking for balls to use on heavy, medium, and light oil.

I appreciate any help.  I've been out of bowling for 10 years and just got back into it 3 months ago.  I am averaging 181 and am excited to get some new equipment to try out.
