[Possum]

OK, let's address the concept that I am somehow reluctant to use both hands.

I spent most of 6 years playing FPS games, (that's First-Person Shooters, to those who aren't familiar with the term)

TF (Team Fortress) was my game-type of choice. TF is a series of mods for various engines. Essentially, the TF concept is a class-based variant of CTF (Capture the Flag), involving 9 classes (Soldier, Demoman, Heavy Weapons Guy, Scout, Spy, Flametrooper, Medic, Engineer, and Sniper). I led and co-led several different clans. I played in two different leagues, albeit not at the same time.

League play involved 2-4 hours of practice 3 nights a week, and then a game on Sunday (usually).

I list all this only to give you some idea of the dedication and seriousness I brought to this pursuit, and also the hours committed.

Nobody ever, ever, ever played any FPS game competitively without using both hands. It can't be done. Period, end of sentence, end of paragraph.

I spent years using both hands furiously, to the point where I wrapped my left wrist with an Ace bandage before playing, simply to limit range of motion, and avoid RMI injuries.

There were weeks when I spent 25-30 hours or more playing TF. With both hands.

Am I making my point here? Your "use both hands" routine is so much hogwash.
