I've put close to 10k on my corbin dished, and I must say, it's a bazillion times better than the stock, I really don't notice the issue of sliding forward that much, and don't have any issue sliding back on the seat when I need to. I will say I had fun breaking it in, but I wouldn't trade it for anything. My longest trip wasn't really far, but it was almost 8 solid hours in the saddle, I was impressed to say the least, no butt buzz when I got done. The real test will be next may when I do my 1000 mile day, backed by 2 500 mile days all in a row.
