Black ... white ... black ... white ... darn it, I can't decide!
I just got some of Rich's white Missouri flints and some looked amazing and one was down right butt ugly. So, I 'tried' the ugliest first and she went off almost every time. I think they will be 'arm' dependant, as my Wilson has a VERY short hammer throw and I need my flint et al to be optimum.
I will say I just bought a dozen from Track (Tom Fuller black english) and they were UNREAL in unformity and geometry. My Wilson was 100% last SAT with them and I never knapped for 30+ shots, I just cleaned theflint andpan every 5 or so shots.
For the price, I believe Rich's flints are a superb value. I do believe that I need to spend more time with them and I would urge all posters to try them out! I'll try them some more and report back.
