Glitch's latest submission:
I love this design.
You have my vote.
The fonts may need a little tweaking, but it's still great.
Also, maybe it's just me, but I think "Nuts & Bolts" should be associated with something rather than just hanging out there by itself. Maybe something like, "The Nuts & Bolts of Texas Hold'em."
*EDIT*
Also,
maybe you could find a way to work in the revolver. But this is more of a thought than a suggestion.
