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.
