How committed to new boo are ya? I only ask because I was on a similar journey until a few good buddies pointed me toward some vintage boo, and I ended up finding in pretty short order a '69ish Orvis Madison 2pc/1tip 6'6" rod for a steal. I would happily pass along the websites I cruised looking for a used rod, along with some sites listing new builds at a really fine price (domestics).

To answer your question, no, I don't know a darn thing about headwaters sticks, but feel free to PM me for info. Is there a particular price point or window within which you're operating?
