New shape small sail

Hi. Just wanting to know what the new shape small sail is like and if anyone has any recent experience?
I struggle on an inland water in anything above about 13knts (gusts above 25knts) mainly due to rapid shifts and turning me into irons. I am a relative newbie and weigh 70kg and have a MK2e with the new shape sail. I can keep up with others in lighter airs.
I am working on my technique but getting frustrated; will the small sail be the answer in heavier airs, I'd rather not splash £1k if it is not going to help? Thanks John
