just wanting to know how do loft switch blade sails 7.8 2013 work on a n/p x6 sdm mast

Hi,
Just need some urgent info , was wondering whether anyone can help.

I am about to pull the trigger on a 2010 Neil Pryde H2 6.7m sail for a decent price.
This uses a 430 mast.

I have an older Sailworks 75% 430 SDM mast, will this work decently with this sail?

I have emailed NP direct but havnt received an answer as yet, I know this sail will be sold shorlty so thats the reason i am asking here

Thanks guys

btw - who stole all our Seabreezes this summer :(((((

i have a KONCEPT 5.0 and rig it on a RDM, it's a powerfull sail and has a great range and would equal a freeride 6.0, on the water it's as light as and very twitchy and unless your fully powerd up say 20 to 25 knts its very tricky to jibe and theres no room for era, it feels like i need an extra 6" on the boom and leech,
has anyone found the same problem
the sail is rigged on a loft 400 RDM 100% with mini cams and neil pride cam spaces too compensate for the RDM
