I hear ya. I never had a Mustang, but always wanted one (they didn't make one for my last bike), so when I recently bought my SERG, I ordered one (2 pc Touring one w/rider backrest), and was a bit let down. I picked up the bike and rode it home 1,300 miles in 4 days (2 up), and after the longer days, I was a bit sore, and thought it didn't leave much room to move around (locked in one position). Being a Corbin fan, I think it's too soft.
So, I just sent it off to Mean City Cycles-it's going to get a firmer memory foam, narrower nose, and I asked for it to be slightly lower and back. I sure hope I'll be happy with it when I get it back, after spending so much on buying it, then having to modify it.
One good thing- my GF likes her seat (the 13" wide pillion), so no mod's necessary for half the seat.
BTW Fuzznuts, I saw your ad, and thought you missed a number in front of that $_75.00.....what a steal for somebody!!
