Didn't have time to read through all the threads, but there are saddle test programs out there.
WTB
Terry
Selle Italia
all have test saddle programs. You go into the shop, pick one out, take er home and try er out, and swap around until you find a prince in the sea of frogs.
Our shop currently has the WTB one, but as soon as the Terry Selle programs come back into stock, we will have them.
So see if you can find a shop that has one of the programs. I'm thinking Terry might work for you.
good luck!
