www.mackiteboarding.com/02-cabrinha-mantis-windowless-wing/The v1 handles were very good in my opinion and these new handles look even better. I also like the additional dihedral and I've been preaching for more dihedral in the large sizes for a while. Bigger/better bag is also a much needed update. On the other hand, the pricepoint of the original Mantis was a major selling point and it looks like prices have increased quite a bit ($100+ for all sizes) in the v2 with only minor tweaks. Would have also liked a dump valve on the strut.
v1 was a great wing and it looks like v2 improves in the right areas without overcomplicating anything.
