Thanks for the pictures, do you really need the tack line on a 2-1 block or can it just be run 1-1, without the back to back block?

And to keep me from kneeling on the halyard during a snuff, I was thinking of only running it half way down the tramp, throug a single block tied to the mid point foot strap, then over to another single on the other footstrap, then forward through the gromet to the bag under the tramp. I want to keep as much line up front as possible, so the sheets don't get tangled up in the halyard during the take down.
