I know this is probabley against the general view held by most...
When I was there in winter 2000, I couldn't fault the quality of instruction by Steve Fisher. Didn't fly with John or Richard who where the 2 other instructors at MLB apart from the odd check ride.
I found Steve & Antonia very likeable, they even offered me a Job with them! Sadly illness prevented this.
Steve's instuction was first class, yes he's hard & he'd tell you straight to your face if your crap or avaition isn't for you. BUT he's a master at bring out the best in those who have Talent.
Just my views, you will just have to make you your own minds.
