I've sailed the NP H2 sails a lot this year in Rhodos. They are very good, very light and very early planing sails.
Very smooth camber rotation, you hardly notice they are there.
They also need very short masts. With a 460 mast you can go up to sail size 8.2m2 !
This is all exactly what you want, I think.
BUT, they also need masts (like most NP sails) with a lot of flex top. That's where your mast probably does not score well. And yes, there is also the price ... What can I say ...
You can always go to the shop and take your mast with you. Just try it out.
