Forget RA numbers, they don't necessarily translate to actual feel, but IMO the BP feels stiffer than most of the "control" frames out there. Similar to the last gen Radical Pro. MUCH stiffer feeling than the regular Blade 98.
its not stiff. at all. prob 63 RA or so. but its about 340 + or so swing weight. and is very demanding to use. very daminding to get sufficient rhs. small ish sweet spot.
