Re: Double VS. Split Backstay
Don't give up the adjustable backstay. It's a very useful control, even for cruising, and when the wind speeds pick up it will allow you to keep weatherhelm down and the boat on it's feet. Even if you don't use it now it doesn't hurt you to have it there.
If you remove the adjustable backstay then I'd leave a split so that you could put the adjustable backstay back on.
