Hi all, I pre-ordered a pair of Atlas Deltas in Jan, and today agreed to sell them to my friend for the purchase price when they arrive, so that I can buy a pair of Masters instead. What would you say are the upgrades, and how substantial is the upgrade anyway, what do we know so far? I was so up to date and on the ball with the Atlas Deltas I cant be bothered going back and reading all the forums again to get information on the masters when most of the people here probably know it all already, I know myself I was always ready to jump at the opportunity to tell someone about the atlas deltas.
