I just got into shooting traditional by building a laminated longbow. It shoots great but was wondering how much of a speed gain I would get by switching from B-50 to FF. It has reinenforced tips so it will take FF, but is it worth it? I know, speed doesn't kill but if I can flatten the trajectory a little I might be inclined to give it whirl. Also does any body know anything about B-75? I havent been able to find any info on this material,like can it be used the same as B-50? And what kind of performance characteristics does it have? Any information would be greatly appreciated.
