I've tried most of the big name quivers and have settled on Great Northern as well. With the top and bottom piece being joined together, they really can't slide much, if at all. Super easy on & off as well, plenty of room without being bulky. I was actually messing around with an older bow yesterday and started putting a slide-on on it, and after trying to slide it down further into the fade-outs gave up. 30 seconds later, I had a great northern on it without having to jump through hoops or get another work-out in for the day. The only "issue" with them is that the arrows on the inside/bow side of the quiver can be tough to get out if you need to get at them quietly, but with the 3 it holds on the outside, that has never been an issue for me.
