Playing in a 2/4 limit game I would really be bummed up at having to pay $40 for four hours of play. 3/6 not so bad, but in a 2/4 game you better win a good share of the pots to make up for the $40

Just me thinking out loud. But I do like to sit down at a 2/4 game and play for four or five hours. Just a nice time socializing and meeting people. Plus it keeps me from losing the farm at the craps table in less than 45 minutes.
