I Have unders, i had no choice but i am glad in away as one less thing to consider or make a decision on, i think i have heard that if you have unders, you can’t go over? not sure if this is factual or not. Unders are more painful than overs, but i also think it depends on your pain threshold. I really like my unders so can’t say which i would have gone with given a choce, i’m thinking most people will probably say overs though, hope you get more answers to this hun.
