well keep at it, you're good at them!
kick combo was rather short for a combo, but there's a corelaunch, so I gotta love it. there's ghosting in the opener, though. But man, I can't make a corelaunch, and I've played for soon to be two years!
As for the boomkick, arm and pec is the easiest combination, and a split or decap usually tags along. Sure it's a boomhit, but the second-lowest "rank" there is. not bad though.
