I would be worried trusting my skull to this guy. He may be good in other areas of plastic surgery, but sounds like HT is not his cup of tea. 80% is very low in FUT. 2 microscopes is not many for mega sessions (2,000+ fu's), they usually have 4. Hairs are suppose to exit scalp at an angle, not straight up, to give better illusion by reflecting light.
You give the impression that you feel this guy is less than forthcoming with you. Trust you instincts. Get 2nd opinions, even if online with several known clinics with stellar reputations.
P.S. There is another member on here that had a family doc refer him to a HT surgeon and the result was unsatisfactory to him. So much for the family physician being the best for referals.
Cheers!
