In reply to shipton47:
I've got both the OMM and the ME. The stretchy-ness of the OMM was the reason I got them but the fabric is pretty sweaty. The ME aren't stretchy but the cut negates the need for the stretch and the fabric is a lot better/nicer. My choice would be the ME ones.
Caveats - the OMM ones are quite old and the fabric (Gelanots?) might have improved. Also, I lent the OMM ones to my partner for the Highlander, I wore the ME ones and we both were similarly satisfied with the performance/comfort.
