In short a lot...So just how many "angles" are there in a saddle set up?
Ken is right. You learn to deal with it. Eventually you barely notice it.Look at bridge length, tether height, body posture in relation to tree, placement of saddle on your but, etc. Body size and shape can have an affect. Many of the angles change if you bend your knees and rest against the tree. So many variables, just keep playing till you get it right. All saddles have hip pinch, some worse than others.
I find that a hookup too high - higher than eye height if i'm standing up - causes a lot of hip pinch and general discomfort. Anything lower than that though is generally fine.
