I'm a firm believer in the Dark Matter and my riser only has a small amount...my next riser will be all DM...
Much better looking than most phenolic that has the grain in it, and heavier. Puts the weight right in the grip....bow still feels very light, but even with a Thunderhorn Small Fry strap on quiver and full of arrows the bow balances perfectly....no left or right. This is probably not due solely to the DM, I'm sure Jim's grip and thumbrest contribute also.
I would also go with the XTL lam... Quieter bow IMO....
