I bought a "Comfort Max Ortho-Deluxe" gel pad with a tailbone cutout. Took it on a 675 mile ride last Friday and Saturday and it is a 100% improvement over the Airhawk I had used previously. It doesn't eliminate the tailbone soreness, but it reduces it to the point that it is tolerable for extended periods. It does retain heat, and it raises you about 1" in the saddle, which might cause some buffetting. But overall, I rate it as a significant improvement. Purchased it from American Motorcycle Specialties USA, Inc. Not cheap - $140 with shipping, but worth it IMHO.
