I love my Drakon and Lite 209 (Drakon on the road bike, Lite 209 on the back of the tandem). Yesterday I rode 27 gravel miles on my CX bike and decided that I am no longer willing to have broken labial skin and burning pee...or need to shift and squirm for entire rides and avoid the drops.

Looks like the Glider would be the best option that wouldn't be incompatible with rolling mounts/dismounts (that upward flare of my other 2 saddles could make getting on/off the bike a bike sketchy, I think).
