i discovered with my thin bridge Asian fit fit me better. Bought of bunch of pads to switch. First 2 switches went fine ...Grey Smoke pads would not come off Turns out its a nosebomb shaped piece of hard plastic there not the 2 prongs newer ones have sometimes...Many of my older pairs are like this all purchased from Oakley or Zappos... and i was only able to switch on 1 custom Black/Ice and 1 Polished Black The Matte RB were grafted on and u could feel it was solid underneath. O denies this and after mine were ruined says every pair is switchable..This is NOT true....Bought replacement Grey Smoke on Ebay for 94 shipped but really frustrated by Oakley- NOT every SJ2 has switchable nosepads!...Has anyone else anything they can add...please
