First crack at the 3.1m Paia today. Zero experience on any double skin before this.
Tried 2 sessions. 86kg rider on 68l 6'5"x19" Sunova Pilot. 700 enduro with mako carve pro 125 to start and then the silk 1050 with ug39 second. Nasty wind range.
Launching the Paia: I thought this would be hard but it's not bad. It's just a two handed launch, hold the canopy up, let the water drain, then toss while holding the bar with one hand seemed to work well for me.
Getting on foil: I also thought this would be tough, but it seemed that pointing myself downwind with the swell generated speed quickly and I was right up onto foil.
Going upwind: This is what I thought would be easy, but turned in to a total fail for me. Every time I angled upwind I collapsed the lower wingtip and the canopy turned into a ball of fabric and I fell over. I called for an assist after my session was done and was told the bar sensitivity is very high and that you need to keep the canopy higher than you'd expect. I was keeping it right next to the water which may have been why it was collapsing.
Gust management: This was the most impressive. I was also testing a brand new 1.9m single skin at the same time. The 1.9m was unusable for me. I couldn't control it at all, absolute violence in these winds. I never got on foil with it. The 3.1m Paia though, never jerked me, never felt out of control.
Overall: Despite not having a successful day of foiling, I'd say I had a successful day of learning. The Paia seems like it is a super high tech option that will require a bit of training for me but I could sense that something special was there...

Also, I forgot: Collapsing via the A lines or backstall is a joy with the Paia. The A-Line collapse brings all battens straight to your hand. No management needed. Backstall doesn't overpower either.
For those who are more seasoned with the Paia sizes: Has anyone maxed one out? Felt like it was too much? I'm just wondering if these have far more top end than Gregs chart shows on the BRM website.
