Dont know what he is like as an instructor but he does some serious diving and is a IT for TDI and IANTD so presume he is good. Looked at the website and it talks about the predictable manifold shut downs and gas sharing and ascents and the like - pretty standard stuff - think the most important thing is ability to be neutral - buoyancy - and getting your bag up well - thats all quite basic stuff for the tech diving and presume he'll give you good pointers on the newer stuff. Why dont you just give them a call and talk to him.
