I usually had yong crew on my I 20 and the Jav 2. The spin halyard going up was the biggest problem but I found it much easier when I tied a larger block to a foot of line through that tiny cheek block on the mast.

The larger turning radius and free moving block on the line made it much easier to get the halyard all the way up. I tied it just long enough so that if the block on the bail were straight up, the two would not touch by about an inch. I also put a little larger diameter block on the forward beam where the halyard came down, on the way to the back of the tramp. Just having a larger radius turn made it easier to haul up.

The foot long line off the top cheek block also saves you two feet of halyard flailing about when the spin is up. I believe this is how some of the Europeans rig their F18's, at least that's what I was told.
