I've heard of him.
Never heard how he ran his airtanks though. I figured out a similar sollution all by myself
In the old school days of tournament play I had two 20 oz tanks in my back and carried 12 x 100 round pods, madness!
Only reason for not doing what he did is that I like my MPM gas through stock way too much. Keeps the gun light as possible, great when shootin 1 handedly from those wacky positions
