Review is great as per Gav's usual. but I reiterate again my opinion about the upwind capability of the PP which is not that far off from the PR. Whoever comes from BRM Kanaha's and Ka'a learnt the hard way. Basically riding parawing on front lines and sail at 40-45deg. I have seen people reaching unreal angles, even on the Ka'a
also the review does not mention the much improved construction of the PP. It was reported in multiple venues how battens stitching and trailing edge of the Pocket Rocket developed issues over time. The PP addresses both.
pull wise there is no comparison. The PP starts earlier than the PR. Once again it is a matter of habits and people coming from BRMs will have an edge. With the PP sail has to be placed deeper and lower in the window compared to the PR to take off.
i am the guy outside the chorus here, and probably it is due to the condition specifics I usually ride. The PR in sizes 4.3 and 5 turned very poor, it was really bad for quick retracts and redeploys and very prone to line tangles. The PP improves ALL these issues.
