"Some".
In general I think it can be hard to find many saddles you can just test. Because the shops that do do this, won't have every model.
I did find an online retailer that said if there are no mounting marks, they take it back, if there are, they do but keep some of the money. So I will tape the crap out of those rails to test a few saddles.
