i have the bbr and yes it very soft probly the softest and no the patch does not fall off i ride in jeans and mx pants and shorts and i move around on the seat more in one ride that the rest of this site in one year
I swear my CEET tall seat foam is as hard as it was the day I bought it. I have had it over a year and its still like 2x4's. I got used to it after a while. Since it doesn't let you sit down in it you are sitting taller than most tall seat foams. I don't think I would trade it if I could (probably say something different if I had just been riding for 2 hours). Anyway I feel I have more control of the bike with it because I am sitting on the seat rather than in it.
If your seat is hard do what Ricky Carmichael's old mechanic Chad Watts did, take a knife and poke some small holes in the top of the seat and put the cover back on, you can also drill small holes if its serious. There is all kinds of different seat variations the pro riders use. Chad Reed uses a step up type of custom seat to keep him in "the saddle" and Kdub uses strips from extra seats to creat a ribbed effect for his pleasure. Anyways hope this helps.
