I have it and I like it. So does the GF who handles it with ease. (the Mainsail..)
There is some loss in performance I suppose, But I dont sail a race boat and I suspect the sail lasts longer as its not pulled at the foot while under sail creating a bag out of the sail.
That said when I take off in a few years I can and may revert to a more traditional set up..
