Hardhed, If you prefer Martin's Savannah over the Vision, you may or may not like the Bamboo Viper. The Bamboo Viper riser has same grip as the Vision & the limbs have simliar geometry. I've heard someone say that Martin will also custom make you a Savannah in carbon backed bamboo. I'd love to see pictures when somebody gets one of those little babies. I own both the Savannah & the Bamboo Viper. The BV is still too new to me to say for sure, but right now I still favor my Savannah. The Bamboo Viper is a wicked looking bow, though, and it seems quicker than my Savannah. Both are marked 55# @ 28", but I don't have a bow scale or a chronograph. Can't go wrong with either bow, in my opinion.
