[Translation of the original French comment]
After 3 years flying a Mars 170 and 5 flights on XS i made 5 flights on a laminar 14R.
4 in thermal condition and one in pure constant wind soaring.
The wing is very stable and pleasant on first contact. Nothing to do with a XS. I needed one afternoon to fly slow and stabilise into the thermal.That's pleasant.
It's pretty easy to tighen and then flies pretty stable. During accelerations it' s the same, quite stable.
Landing is really cool: 30cm tighened it goes fast without stalling too early tho. Not tighened it seemed slower but still stable. A great wing i think.
