I have the 4 to 1 jib luff tension device on my nacra 6.0 and am unsure how to tie the loop in the jib halyard so it will pull through the block on my bow foil and attach to the hook i have on the tension system. A knot is to big to fit through the block and i dont think i am goona be able to splice the really small covered line for the halyard. Also, how am i supposed to pull the eye where the halyard wire and halyard line connect through the top of the jib where the zipper starts while it is mid way up the forestay? Any and all help is appreciated.

Get a 20' (or whatever you need) piece of the smallest dyneema you can find, use that instead of what you are using now for the loop + knot, then tie what you are using now to the tail of the dyneema after you have done the up-down thing, as you will need some fatter covered type line to hold in the clete.
