I'd probably compromise and leave it right in the middle.
Get a baseline for a wakeboard wake and surf wake that works for you and then fiddle one way or the other and see how it effects it.
I can get both a nice surf wave and a nice wakeboard wake with it even with the hull of the boat, but since I don't really wakeboard any more.... I just put it all the way down to stretch that surfing wave out (and then use lots of weight to make it big and steep.)
