Some good reading here:
Do you find your S-Type 9.5m has a lot more power than your Ram F10 9m? I been thinking of getting a S-type 9.5m just for super light days:)

Mark, thanks for your reply.
And yes there is much difference in lowend power. The Ram is more stable in the high-end and the S-type has a massive power in the low-end. You can see the difference when you rig the sails. The s-type has much more a belly. The RAM is more flat
I like both the sails very much. Easy rigging and both stable sails.

Excellent news because I bought the S-type 9.5m this morning:) I love my Warp 9m/iS137, but at 100kg, it is best in 12k to 20k warm winds, lower winds feel slow and underpowered. Hopefully the S-Type 9.5m will solve this problem out. My Warp 10m is high wind Formula, so it is no more powerfull than my 9m Warp.
