weeellll, they kinda turn out ok
if yer into plywood bows , that is
they turn out great- and awesome shooters- i have always been wary of the clamp ups, but i think i am just not smart enough to get it to work- but man o man they work allright- i have an ol' codger bow and it does 174 fps with a heavy hunting arrow- only #50 at my draw!
