Got the 7.0 M3 (X6 430 mast) out on the water today with an I94. Was using a select 35cm fin. Great low end, (absolutely has power of a 7.2/7.5) was up and running in about 13/14 (Im about 87/88kg). Very easy to use rig and quick,light in the hands. As the wind came up just cranked on a little more outhaul for reaching and let it off again for some speed runs. When the wind picked up it was 16 - 20 knots. As far as times go I went faster on the 7's 1st real session than I have ever have been on the 6.7 RSR, so not bad, infact equalled my best time sailing a 6.2 RSR in wind from the same direction, so I'm impressed.

Here is my GPS posting

I rigged the 6.2 on both 400 & 430 and they looked the same, perhaps because its a progressive curve. Hence decission to rig on 430, and now no need to get 460...great!
Now cant wait to try ther 6.2!
