I see I'm not the only one with this problem, thanks for the input so far. To comment on a few of your replies, I'm pretty sure I don't want to size down to a 650b wheelset. I ride a 61cm frame with a size 15 foot and have no problem with toe overlap whatsoever. That and the Warbird will clear a 700x47-48mm tire no problem if I want to pump up the volume!
I'm also hesitant to try the Rene Herse tires not only for price but I'm afraid they'll be too fragile unless I get the extra protection version which kind of negates the benefits of their products being light and supple.
The 47mm Teravail Cannonball is topping my list right now based on the performance of the heavier 42mm that came on my bike. Lighter, more volume, and a tan sidewall to boot! Not to mention almost half the price of a similar Rene Herse.
I've also had great luck with Schwalbe tires on road and mtb, never a flat and they roll extremely well. Maybe a 45mm offering from them could work too?
