Adjustments to an odd structure

[MrG]

Blinds are 1.00 and 2.00 but minimum bet stays at 2.00 throughout.
The turn and river bets are NOT 4.00
Tables full of very loose players(5-6 to the flop, frequent cold calls, people going to the river with like J2o with a board of A T 4 6.)
I sat for about four hours and won but felt I could have won much more with a few adjustments.
I am trying to think things through this morning. Any and all suggestions welcome. Thanks, - MrG
