Which line for a mainsheet

Fair leads,

I have mocked up adding a block to my fiddle blocks and everything runs smoothly so I am getting close to implementing this with the 3:1/6:1 coming off the boom. I am settling on 5/16 XLS as it seems to run smoothly and does not have the pick issue. The size seems like a good compromise between something large enough to grab and small enough to run free. Half way between the 1/2" I had and the 3/8" you suggested.

My remaining question is how to cleat it for a race situation. For cruising, I will use the existing horn cleat for one end and the existing turning block and cam cleat on the cockpit sole for the other end. For racing we don't use the turning block as it is just too slow, which is why I happen to have two ways to cleat the sheet right now. For the new setup, one end can go to the main horn cleat but what about the other end? Should I add a second cleat or perhaps a pair port and starboard in addition to the main centrally located one.
