TB.....if you commit to the ouside, buy a urethane ball. Good ones out on the market. If you commit to a swing shot, on the oil , then out to dry at the back, look for a high rg ball, that will give you a good flip at the back. Sounds like you are playing on extreme wet/dry or Top Hat. This is the worse condition ever. The young folks around here, just try to ride the oil line with lots of speed.
