Help! My seat is killing my back!

[O's Fan Rich]

I bought a new SG and it's made for smaller riders for sure. Spent some cash and now it's a perfect fit.
In my signature there is a list.
I'm 6'4 260... long arms.....

When looking at seats don't forget that the Handlebar length and position can also contribute to back and shoulder pain.
