Well 2.30hrs later and 7 rig changes I think I have something that works..

..needed a 'snickers' half way through or I would have killed someone..

.I'll thread the outhaul through better when I go to sail.
I ended up replacing the ropes that go through the little pully and cleat off with longer ones ( formula line) as the ones I had weren't long enough to let the outhaul off enough to take off the clew fittings when derigging the 7.8m..I'm not using an applecore just the cleats the severne sails have.
One problem is the way it is threaded at the moment it pulls up on the clew ( rather than down) so I've had to use an extra hole in my extension so the clew didn't fit hard against the end.
I don't know how you use the elastic cord for the ends you pull on as if I have it ok for the 35 ext it has big loops for the 10 ext..doing from 7.8m sails to 6m.
I also put the cam cleats a long way towards the boom end . I was sick of the other ones getting in the way when I gybed.
They may be too far away to be able to lift the line up out of the cleat. If I move them closer to me ( in) will that stuff up all the measurements I've set up?
I've left all the excess lines just hanging so I can adjust if necessary..I might also replace the blue line with formula line so it will be more slippery..

I need a rest now..
