Sorry for the necroposting, but I want to share my new experience on this topic.
In the spring, I started learning knee launches on a PNG 1150. It turned out to be quite challenging; even after many attempts, it felt unstable. I went to the seaside, tried launches from rocks, and came to the conclusion that for my experience and weight, the 1150 is barely enough. The slightest oncoming wave makes launches practically impossible.
I recently received a PNG 1400. I chose it because it was supposed to give me the ease of launching I’ve been missing lately. And I want to say, it’s the easiest to launch in the current Axis line (the 1310 might be close, but it’s an outdated wing).
I use the 1400 with a 560 fuselage and a 35 skinny (105 area). Right now, I’m getting good knee launches, and they’re much more stable than with the 1150. I can launch from a running start with just one step. I’m also currently learning drop starts.
But I’m not super happy with how this wing pumps. I compared it to the 1300 v2—the 1300 pumps fun and easily, and you can use both a wide and a narrow stance. The 1400 requires much more precise foot placement and a narrow stance. But it also feels like a trampoline, which is cool. And its maneuverability turned out to be better than I expected. I had experience with the 1401 (640 fuselage and 45 skinny), and it seems that the current setup with the short fuselage is more maneuverable than the one with the 1401.
Summing up my experience, the 1400 is well suited for launching from new places. I hope that Axis will release a wing with a larger span, something in between the Fireball 1750 and the PNG 1400.
PS: I upgraded the fuselage from a 640 to a 560, and I’ve only had positive experiences. Launching hasn’t become significantly more difficult (even on the Fireball 1350), but it’s had a positive impact on pumping. It’s easier to accelerate and gain altitude. Some people said that glide is harder with a shorter fuselage, but I didn’t find that to be the case. So if you’re considering a fuselage size purely for pumping, go smaller.
