Either pair. Don't listen to the clowns that claim the PB2 is in no way a successor for the PB1. Same exact features of the PB1 mixed with the premier tech that Oakley has used for decades... Don't see how PB2 don't work.
1 and 2 fit differently. I would try them both on and see which you prefer. I favor the look of 1, but cannot wear them due to fitment. The 2 fits me like a glove, so I went with 2. Just get the one that fits you best if you expect to wear them.
