Nukeproof scout 275 to 29er mullet?

[beanzz]

So I'm thinking about building a scout up and there is a particularly good deal on a pair of dvo sapphire forks but they are 29er, and the 27.5 scout frame is 200 quid cheaper than the 29er.

There seems to be very little information on it, but as far as I can tell it would slacken the head angle and seat tube by a bit and shorten the reach by about 18mm asking with raising the bb.

Any help would be appreciated
