Thanks for all feedbacks !!
My first feeling would be the Vapor, but its the smaller one with a 460-25 IMCS mast.
RAM-F8 is also 4-cambered but bigger. It's not a WARP, but it can be used with a 490-28 IMCS mast.
TR-4 needs its a top tip mast, too specific mast !!
I'm agree to get the most powerful, but I don't which is the one: some times some sizes are not the best in the same family (for example seems that RS-S 6,2&6,8 where better than RS-R same sizes on 2007).
