In reply to estivoautumnal: Obviously that's the right answer, and I will, I have tried the extremes and they fit great, about to try the evos early next week. I guess I am saying if they both fit well - then what, the evos can be had for £310, but the extremes for £270 ish. Lighter and warmer sound good and in the long run its a sound investment, unless users have noticed other issues or differences.
