I believe the riser wood in the pics that Gregg sent me are cocobolo. I'll ask him the next time we talk.
Robhood, that is a beautiful bow, and a great buck!
I would advise talking to Gregg about which bow may suit certain needs better, but if you like a little shorter bow for hunting, or have a bit shorter draw length, the Elkheart would be your best bet. If you don't mind a 58" or 60" bow, like a little more mass weight, and have a draw length a little on the longer side, the Falcon would probably suit you better.
I know that the shrews and Java man bows are different, but I draw just a tad over 28", and my 58" super shrew fits me wonderfully. That being said, I shot a 54" Elkheart, and couldn't for the life of me feel a difference in fit. And it was a tad smoother, quieter and faster to boot. He's starting on my Elkheart as I type this.
Call or email him! You won't be disappointed.
