Good

Great punch, low sag, low weight, but low capacity.

High intensity moves are no problem. These are great packs, just know if you're really ripping, you won't be in the air for long. If I'm pushing hard, I'll only get 2 and a half minutes on my 3. 5". The low weight is incredible but comes at the cost of flight time. Can easily get 5 minutes on a cruising flight, and 3. 5 mins on a moderate flight.
