Steve, in all honesty it boils down to personal fit and design. All of mine were made specifically for me, except for "Quiet Places" and Nate is giving it a facelift so it will, and so they simply work better. We've mentioned this before, and I'm sticking to my guns...perfect fit does matter with this style bow! You never see them on the classifieds because once they get in the hands of the person they were made for, they never leave. The couple of folks I know that didn't love them got them used. Why didn't they like them? Because they weren't built for them!
I don't know of a bad Hill bow being made by anyone out there - I have owned and actually "like" them all, but I "love" these. Nate specializes in string follow bows and his designs and construction techniques are different than the others, and simply work better for me. If you need heart surgery, you go to a heart surgeon, and not a general practitioner. Same here...if you want a reflex or straight profile Hill bow with exotic risers, various core materials, pretty veneers, and tip overlays, then Craig or Steve are the guys you need to be talking to, if you want a split bamboo like Howard's original bows, then David is your man, but if string follows are your passion then you need to talk to Nate!
