Thanks pal. I think you're definitely safer doing your own stuff if you're confident, absolutely.I've seen a few horror stories like these for the past few months, where tune ups get stuffed up and pairs got 'lost'. It looks as if Oakley trainees are running the show around the world and the old school technicians have gone into retirement. So sorry to see you got the raw end of the deal.... i'm just thankful I do my own tune ups and don't have to trust some random tool with my treasure.
The nose bridge for the carbon looks like cosmetic damage (which sucks) but at least it's not a fracture or broken bridge. Send it to someone competent and either swap the bridge or push the pin back so as to not stick out like a sore thumb. Carbon frames don't vary in color too significantly unless JC juliets are polished carbon....
I may look into the bridge replacement option if it annoys me too much. I'm hoping in the back of my mind it can be out right but I'll wait to hear if this is so. Their assessment and correction could result in a permanently damaged bridge. JC is just standard carbon yes.
