It's getting hard to come by QR equiped forks at the more fun end of the market, but until I find a pair of forks I really want that forces me across to 20mm axles I'm fine riding QR in the most gnarly way known to man.
Oh and second the Shimano skewers. Only really discovered this when I bought a slot dropout SS and needed something that really clamped well. Even the older ones that look a bit basic (well, sh!t.) work well.
I have wondered if part of the stiffness of 20mm most people feel is due to skewers not clamping up as tight as they might be and allowing a bit of extra flex.
