I have asked Dave about this before, it involves a Dymondwood base riser and two extra "thin" lams in the accent stripe for a total of seven lams (FF model) rather than five lams (for B50 Dacron models).
I completely respect what Dave says, however, unless there was an objective test done to prove otherwise, I feel a non-FF bow/riser could handle a FF string, especially if the loops were padded. Having said this...I would not do this with MY Silvertip out of respect and the cost being too great.
My next Tip will be FF compatible. It's not a speed thing but IMO FF bows shoot tighter, quieter and have a better harmonic upon the release. FF strings are extremely durable and have little to no creep.
