i ordered a speedo endurance in my regular lycra size and tried it on today at home... and it fits pretty well except for the bottom part! i'm sure it'll ride up sooner or later and i'll moon everyone. eeks are speedo endurances usually like this? a bigger size would balloon in the water...
I pretty much only wear speedo endurance suits (I have one Dolphin poly too): It does stretch, though slowly, and I do get wedgies. I don't care about the latter since I have mastered the flip-turn un-wedge maneuver, but they do seem to move less than lycra, so the wedgie is not so bad. So I wouldn't worry so much. If you are used to lycra maybe it will seem odd, but they last about a million times longer.
