Do severne sails work with Neil Pryde masts?

[mcross19]

I have just got my hands on a 2011 8.6m Turbo and was wondering if it will be ok with my Neil Pryde X9 490 mast that I currently have. The reason I ask is that I've seen posts on here saying that North Masts will not allow the sail to perform correctly.

Obviously Severnes own masts are perfectly matched to the sail characteristics but I have been told that Tushingham is a good alternative, are there any others? The reason that I ask is that it may be some time before the shop can get their hands on a Severne mast (Red line/Enigma) due to the non existance of an importer here in the UK this year.
