I play red chips in 6 and 8 deck games. I play green chips in DD games. That makes max bet $100 to $150 in 6 and 8 deck, $100 to $125 in DD games. Since I am in AC more than Vegas, I'd have to say I play red chips on average.
I literally stumbled into it. I stopped in to play a $5 freeplay coupon and on the way out I walked by a bulletin board with lots of things hanging from thumbtacks. Most of the flyers were drink and food specials but one of the flyers said 2:1 and listed days and times. I did a double take and then started playing it the next morning when it started again. Played it 7 times before they pulled it. Since that time I have "stumbled" into eight 2:1's and several different types of promos that were valuable. Some of them with player edges over 10%.
