I've known of a few cocobolo risers cracking, and it was generally because the moisture content wasn't right in the wood. It can be tricky--measuring the block may give a good reading, but measureing after it's cut into can show it's till too high. I'm the kind of guy that can tear up an anvil with a feather, and my cocobolo riser is showing no signs of wear and tear (other than a few scratches--that happens when you drop your bow on broom-finish concrete) after 6 or more years of shooting the crap out of it. I'm pulling 66# on it, so it's getting put to the test.

I thought about buying some of the African blackwood for a riser until I priced it--shew! That, and I couldn't find a piece big enough for even a longbow riser. Might try it again one of these days.....

That snakewood is dang pretty. May pick some of that up for veneer.
