Well, I did suggest something in the 2.54 range and low RGs, say in the .020s. (I don't know if Phil will acknowledge that.)
http://radicalbowling.com/balls/rack-attack-solidhttp://radicalbowling.com/balls/rack-attack-pearlMy actual suggestion on Phil's open thread was: "That said, I'd like to see in a future Radical ball that has a slightly higher RG, say around the 2.51-2.53 range, and much lower differential, say in the mid-.020s, but is capable of being versatile because of its strong cover: a ball that you can actually play up the boards, but as necessary be able to swing it -- and not always on low oil volumes/dry conditions. I guess the kind of ball that I'm describing is a bit of an old school reactive (with a symmetric core), but I'm sure it could make some bowlers a LOT of money."
