Just my experience for your consideration...
Background: Due to discomfort I stick to basses under 10lbs and tried quite a number of different bass straps over the last decade+. The Comfort Strapp was my favorite until I bought some nicely padded 3.25 inch wide Fort Bryan F-hole straps (BTW, I have a couple extra). I've used a pair of them almost exclusively for the past 2-3 years.
I have some unusual curved 2" wide leather straps (Performance Solutions, no longer available) that my sister carved and dyed - they are beautiful and I wanted to use them again... but without discomfort.
The positive experience with the neoprene Comfort Strapp made me think about using that material to bolster those leather straps. As a result, I found and bought a remnant 1/4" thick neoprene wet suit material on eBay. It's a dense, firm foam, seems a bit more dense than the stuff used in the Comfort Strapp. (Yes, I realize that strap has give to it, this doesn't, but it works for me).
I cut a 2" shoulder pad and glued it to a strap, and it was a significant improvement. I decided to "go all the way" and cut a second 3.25" wide hunk and glued that to the 2" piece already there. That really did it for me. I used it at rehearsal Sunday night, and I'm quite pleased with the feel. I need more material, but next time will probably just put one 3.25" wide layer of neoprene on the next strap I rehab.
These are the two I've modded so far, I'll get in there with scissors to neaten up the edges. If you have a favorite strap you want to
comfortize, this may be worth your consideration.
