Gaastra Matrix 6.5 or Remedy 6.4
 

I'm looking to maximise the upper wind range on my Kombat 89. I'm 70 kg.

Which sail would get me up on a plane earlier in lighter winds, the Matrix 6.5 or the Remedy 6.4.

If there is no significant difference I would go for the remedy as it is compatible with the 430 rdm already used with my smaller sails thus giving a one-mast option.

If the Matrix is significantly better would I have to buy an additional 460 standard mast or would a 430 rdm mast and 36cm carbon extension be OK?
