My biggest annoyance with standard style sporrans is simply having to close them... Never had a prob getting things out, but trying to snap a sporran closed is why I won't wear anything but a hunting sporran. I prefer stud closures as well, and having spent the entirety of the day totaing a 7 year old through a 10,000 strong festival wearing one, I am doubly convinced. I can open my sporran, pull out what I need, and close it again, with no effort at all.
