It also kind of matters what the opposition is doing, doesn't it?
If everyone else is grinding, you can afford to play conservative and take your medicine. But if you've got people having success by taking chances, you might have to move to answer their move.
In the spirit of the original question, I'd probably take plastic or urethane and come from the outside.
Of course, I also have a very weakly-drilled resin piece that allows me to play a shot on a crap condition, so I'd move there first. But if I didn't have access to that, I'd probably get the non-resin ball and move somewhere everyone else wasn't.
