I had the distinct pleasure of obtaining a nice longbow by Bob Rousello. It's a Kohannah Longbow, 68", 52#@28, Diamondwood riser with stained bamboo limbs.
I've shot Bob's longbows before and was actually thinking about ordering one from him when this one popped up for sale. It is incredibly smooth and comfortable to shoot. The Diamondwood riser (my first) adds good mass to the design and helps keep the shot sequence on line, in my opinion. The bamboo limbs are stained a dark color and are like most bamboo limbs...made for longbows.
I've added a few photos to give you a look. It has to be shot to be appreciated though. It's a mild deflex/reflex that is very smooth. Tips are overlays of red micarta and diamondwood. I'm using a 14 strand dacron string on it now, although it had a fastflight on it when it arrived.
Bob's workmanship is flawless. This is a used bow and looks as though it's new.
