Feeler: Akro Evos #_______-200 for sale?

First my bike is a SDR. Well, my Race pipes came in today--even though I cancelled as my Evos got here first (long story). So, should I sell lightly used Evos to buy the "Race" cans (round cans --#_______-000)?

Is there ANY appreciable difference in sound or weight between the two--or does it get down to looks? Which do you prefer?

Also: Anybody interested in buying the Evos?
