I wore Raybans for 15+ years (before Top Gun), but was given the chance to try a pair of Serengettis on a try b4 buy basis. After the first sector I wondered why I hadn't used them before, and am now a complete convert. The model I have is the Velocity witrh a titanium frame, very light and very strong. The photochromatic lenses are brilliant for 'in and out of cloud layers', although the amber lens takes a while to get used too. But brilliant in the NG and the 777. I have just got a new model - the corsa, with neutral lens but heavier (standard metal) frame. I am very happy with them too, if you really don't like the amber.
