RE: 2005 diamond rapture by bowtech
Not being sarcastic here at all... but if you like it, that's all that should matter -- seriously.
As far as getting a wood grip for it, just head to your BowTech or Diamond dealer and they should be able to order one in for you. BowTech's (or Diamond's, as the case may be) quiver is pretty nice. I've also used Kwikee Quiver's with fantastic success, and you'll hear great things about Trophy Ridge's quivers, although I think they may be a bit pricier.
God bless, and good hunting!
