FWIW, I play in a monthly game that features "old school" Kansas City 2-7 Lowball. It's played with blinds, no-limit, and just one draw. In order to encourage action it's played "open or fold" so that pre-draw the player to the left of the BB must either at minimum double the BB or fold. After someone as opened, subsequent players can smooth call or re-raise. After the single draw the action is on the first remaining player to left of the button who can check-raise the second betting round.
There are only two betting rounds in this style of lowball (pre-draw and post-draw), so the check-raise prohibition: a) guarantees some action by forcing a raise or fold pre-draw; and b) pressures those players who only have 1 or 2 decent low cards but will otherwise be able to limp and draw 3, 4, or even 5 cards if nobody bets.... in this way you also c) ensure that you rarely run out of cards during the draw.
BTW, lowball is a great game to have in a private dealer's choice setting, in most multi-game rotations, and is a great short-handed or heads-up game.
