Re: bokken comparison (long post)
I use a macascar ebony set at home for solo practice, and a hickory set from bear wood products in the dojo and for paired keiko. The hickory set lives in a bag in my car so I always have it for training, and in a couple of years with heat humidity and cold, they've never warped. Very few dents, even doing gatchiuchi (sp), and they stand up well to heavy buki, without shattering my partner's buki. Like em!
