I am pretty close to the op's size at 6'2" and ~275. I had been diving a pair of LP95s (I think they are coyne, but similar to PST). Diving with a 5mm wetsuit, they are pretty heavy tanks. My last 25 dives have been with a set of faber LP 108 I found used for a good deal. These fit my body size much better and have better buoyancy characteristics. They are 8" diameter, so really same as the 95s, but 2" taller which actually seems a better fit when gearing up and reaching valves etc. I am trimming out better because they are not as negative as the LP95s.
I have never dove a faber 95, so that might be a different story.. But for a large/tall dude, I see no advantage in getting a short 95 vs a taller 104/108/112 (OMS 112s are the same tank as a faber 108)
**And if you are in the High Springs area any time soon, I would be happy to let you try out either of my sets of doubles.. I could even put bands on a pair of 104s I have if you want to try that out.
