The main halyard kink may just provide something for the jib battens to catch on as you tack. The set-up of the tang should be with a shackle that has the pin end secured through the top hole with the curved end passing through the next hole down. You will need to load trapeze wires for each side seperately as you pass that curved portion through the tang.
Your shrouds and forestay should attach to a shackle which is put through the bottom hole in the tang. This set-up will accomplish one thing in particular: it will allow you mast to be raked further back, giving you better pointing ability. I am not certain of your jib halyard situation. Are you still able to raise your jib to the point that you have signficant slack in your forestay? That is all you are trying to achieve. Hope it helps. See you at Catfight, if not earlier.
