191 fps is great performance from a longbow - what do those arrows weigh? That 31" draw length of yours is definitely giving you some extra fps. The 'home made' longbow I've shot the most in recent years is 56# at my 28" draw and shoots 500 grain arrows at 192 fps.
10-4 JGray, I'll go out to the shop and weigh one of those longbow arrows, my cedar shaft arrows came in too, they're mounted up with the 175 gr ACE Express broadheads, holy DAMN! what an axe! I'll weigh and chrono one of those as well.
