Larger sail for a beginner

[coolny29]

I started windsurfing 9 months ago, and have windsurfed over 15 times in this period.

I have a Starboard Rio M and a Severne Focus 6.0 sail. In light winds I cannot get into plane do to the smaller size of the sail. Due to this I want to buy a larger sail in the 7.0 o 7.5 range.

I weigh 78kgs (172 pounds). I can tack well and am learning to gybe and get in the foot straps. I will try out my new harness this weekend with the 6.0.

My friendly dealer has recomended a Severne Element 7.5 which has 2 cams or the NCX which has no cams.

In advance thanks.
