I started using the low noise V 2.0 props on my P4S shortly after their release and have been nothing but satisfied with their performance in all areas. Firmware is good and unless there is a major detrimental characteristic that I haven't experienced yet (pinch under 60 flight hrs with them) I'll stick with the 2.0s as the positive characteristics have been quite the welcomed improvement! Definitely has some new zip and movements are noticeably smoother. Would very much recommend earlier P4 fliers give them a look
