A caveat about the SJR: though there is now a body of experience on the use of the SJR for inshore racing and cruising, you would be a member of a smaller pioneering group if you took it ocean cruising. It has advantages for that, good helm balance, low stresses and a mast that is further aft among them, but long term longevity has yet to be proven, in my view. The upper jiblets should be prevented from flogging, by adding little battens to their leeches, and sheeting should keep good control of twist under all conditions - again, in my view as someone who has seen what a great many ocean miles can do to a sail. Soluble issues, but ones to be aware of.
Another issue is that the racing boys urge maximum balance, for maximum performance. When I urge conservatism and caution on this, I tend to get shouted down, but I will continue to urge them for ocean going use, making the balance not much greater than 25%.
So yes, I can see the attraction of SJR, but my personal preference for ocean cruising would be a scaled up version of the high-ish AR sail that I made for Weaverbird as a consequence of my experiences with Tystie.
