Before getting your crowbars, wait a season. Oakley has a new goggle on the way for the 2011/2012 season called the "Airbrake". It has a very similar fit to the Crowbar and looks a lot like the Splice. The biggest feature though is the ULTRA easy lens change system. When I was testing it out, I could change a lens in less then ten secons.
The goggle is going to come with two lenses when purchased. Retail will be around $180-200
grey polarized and hi yellow seem to be the best for the conditions and uses your looking at. the polarized lense is so nice, while the yellow performs well in low light and night. thats the best combo
