The ability to rebuy chips at the table should be available, once the room gets some hours under their belt. Patience
In my experience at Parx, the chip runners and the cage have both been very expeditious in handling exchanges. Missing a few hands is not the end of the world. Chances are, if you just got felted, you prolly could use a few moments away from the action to collect your thoughts and take a breath, any way!
Regarding the low/mid limit limit games. I fully expect that (especially after expansion) they will be quite robust. I can see the base for the 4-8 O8-half-kill is already pretty strong, the 4-8 LHE game will be a staple. 3+ games on weekends, is my line (and I'll take the over), I think once the dust settles, the 8-16 and 15-30 LHE games will become the feature games and remain (and grow) in popularity. Whether or not a mixed-limit game flies, will be dependent on us.
The decision to not spread 2-4 will only help reinforce the existing line up. IMHO, that will be a huge differentiator for this room. Kudo's to Ari & co. for sticking to their plan!
Whoever said that the 4-8 game should be a white chip ($1 chips) game is spot on!!! That's how they play it in LV (Bellagio specifically) and it is a great game played that way.
Ari... this is a great suggestion and I'd like to see you give it a shot. it will "up the action"... like that game needs more action
