Bill,

Having owned a 6.0NA, I'm familiar with the setup that you have. Most 6.0 Owners changed from the cross wire "cheese slicer" to modifying their trampoline with a series of gromets and a high-tech line laced through them. The bottom of each jib block would have a snap shackle by which it would be attached to the various loops of line on the trampoline. Here's a couple of pictures.

Having the jib block lying on the trampoline was never a big problem for me and I never had to deal with the cheese slicer because I was the skipper . The crew always bitched and moaned about it though... However, occasionally a jib block would wedge itself neatly under the cheese slicer and would not come free without going to the low side to manually free it. You can keep that from happening by simply putting the block on a short 3" pigtail going back to the wire pulley. That gives enough separation so that even if the block goes under the wire, putting tension on the jib sheet will pull it clear.
