Looks good. I would alter the mainsheet block cleat up a hole so it is difficult to cleat from the wire.
Cleating the main to windward is a sure fire way to get into trouble, particualy in gusty conditions.
I have never owned a nacra that I could cleat from the wire.
A good 8:1 with tapered sheet is quite easy to hold and easy to cleat when on the deck with the spinnaker raised.
Worth a though. I am over 50 and still hold the main to windward uncleated on either 5.8 or F18.
