Selway offers a "Quick Detach" version, but it's still a 2-piece.
I can appreciate the extra weight, but only if it's balanced. One of my bad habits is putting a death grip on the bow, which causes me to torque. I've modified my grip so I'm barely holding the bow, but if it's off-balance it makes me grip it and I start torqueing again.
I recently recieved an Eric Krewson BBO that's even lighter than my Crusader....man it's a shooter! I reckon I'm lucky--light mass weight bows don't seem to bother my shooting.
