Well first off, according to a couple walking by my mom, I'm all muscle and FIT. Go figure.
Secondly, I don't know about the two leg bounds but like in my two leg jumps I feel I'm putting out VERY little power vs. what I'm capable (or I should be capable) of developing. Is like when I jump I transform myself into a guy with a max squat of 80 kg.
And thirdly, it just comes naturally for me to "move" like that in the one-leg bound. Just like in my sprint, I go short and fast for some reason. I would REALLY REALLY love to use a double arm swing in my jumps and bounds, I guess I need to go submaximally for a while to develop a double arm swing jump, although it feels 100% unnatural and "overloady".
