I've played a decent amount of small buy-in tournys, and I would say no, because the majority of the players at these levels have trouble laying down one pair, and you're going to have to hit the flop in a very big way for those hands you mentioned to be any good......I would say just stick to suited connectors, including hands like 9-7 suited, 8-6 suited, 9-6 suited, etc. etc.
