Wow, I definitely gotta hear about this Northstar bow! My Morningstar is amazing! I actually wasn't sure whether to go reverse handle or SF, as I've been intrigued by both. I've done some research and spoken to a bowyer or two regarding the possibility of building a reverse handle SF and the general thought was it wouldn't work - you'd be giving up too much. If JD's got some faith in it, though, I'm thinking it just might work and work well!
Keep us posted!
