Well guys as i'm progressing in bowling i'm developing an arsenal this is it

X-Factor Trifecta (Second Drill)
Agent
Hot Rod Hybrid


Now I have to get the Agent and Hybrid plugged and redrilled due to span and pitch changes.

Now i'm a little biased to Storm and Roto-Grip but will try anything, and Track is one of the things I really would like to try.

Now i'm looking to build a new arsenal ground up one ball at a time replacing what I have, the Trifecta handles heavy oil for me (well the heavy oil I see) and the Agent for medium and Hot Rod Hybrid for lighter stuff, now i'm looking at an overhaul and could use some help in what I look for.

I'm a stroker that has a bread and butter shot of up boards on the outside but I don't mind moving inside a bit. Now to cover three main conditions of Heavy, Medium, and lighter conditions, what would you guys suggest.

Right now i'm looking at something like this

Heavy-Passion/Double Agent (Storm)
Medium-Machine (Track)
Light-Venus (Roto-Grip)

Now what do you guys think of those balls and what would you suggest, thanks in advance.
