I'm not too sure if not putting in on the sides (only front / back) would cause you to stick or not, i'd say that for ME I would probably hang up more that way. Give it a shot both ways. Just make sure to use alcohol or something to clean the "crap" out of the thumb after removing all tape and re-taping.
I like using it on front / sides, clean in the back. I can advocate on that.
I personally don't see any benefit to adding tape in the BACK if the thumb is a correct fit in the first place, the frankentape I use in the front / sides is only to "fine tune".
Hope that helps or makes some sense.
