The reason I play 54s+ on the button or CO is because there are more possibilities for the OESD.

Flops for 54:
76x
63x
32x

But the best draw flop for 32 is
54x

And 43 is
65x
52x

I aggree with everything you have said zook.

By the way, you aren't Ron Zook, the NCAA football coach, are you? :P I go to UF, and poker as a hobby might explain the lackluster performance before he was fired.
