Mine is retardedly complicated. And I don't have pictures.
On my boat:
The tack line drives everything for the take up system. It makes a loop which is tied off to the eye-strap that the righting line ends at. At the end of the loop for the tack line is a back to back block, with the tack going through one of the sheaves.
The halyard goes from the cleat, to the eye-strap on the top of the front beam, then through a grommet in the tramp to the underside. From there it goes through a pair of Harken micro blocks, (I'd recommend a ring for both). Then back up through a grommet in the tramp to the topside, through the block on the tramp, then under the tramp again to the spinnaker bag as the retrieval side of the halyard.
The two micro blocks that the halyard runs through are tied off to a single piece of shock cord. That shock cord runs through a micro block tied off to the rear beam on the port side, and the loop end of it goes through a larger block, which is tied off on the port side. The end of that loop of shock cord goes through the sheave on the other side of the back to back block that the tack line runs through.
So when the spinnaker is snuffed, the tack line is pulled into the bag, which pulls on the back to back block, which has the shock cord going through the other end, which both ends have blocks that the retrieval side of the halyard runs through.. That pulls the halyard from two directions keeping it tight to the tramp.
Sorry I don't have any pictures. My boat is in pieces and hanging on a rack at work for the winter. I really like the setup I have though. Miles of slack when the chute is up, but nice and tight when snuffed. It's my 4th generation of tinkering and running it under the tramp, and by far the best setup I've done.
Check to make sure everything is running cleanly. On my boat, the halyard is the closest system to the tramp, (maybe not mast rotation, I can't remember). Everything else, (trapeze bungee, righting line,etc) are under it. It doesn't take much friction from the halyard being being pinched or wrapped around something to make it a real bugger to get down.
