7-A Five Card Draw

[Notorious G.O.B.]

This game's sprung up on the Boss Poker Network, anyone want to comment on proper strategy? In case you don't know, it's five card draw played with a stripped deck. When four handed or less, all 2's-6's are removed. Five handed, the sixes are put back in the deck. A789T is a straight unless five handed, in which case A6789 is a straight instead. Thanks.
