I seem to recall that there was a thread round here somewhere with an idea for knotless end cap attachments. But no way can I find it now. Anyone else seen it or was it my imagination?

That looks interesting too Skunky. But I found the article I was looking for:

I had a go at the "Durants" idea this evening. I drilled through one set of my Rev end caps and fitted them with new 2mm shockcords with the knots inside. It took a little bit of fiddling around to get the shockcord lengths right. They were 250mm for the wing tips, 220mm for the top of the uprights and 350mm for the bottoms of the uprights. 2mm for the shockcord was about the max as the knots only just squeezed down inside the endcaps. There are both pluses and minuses from what I can see with out a fly.

Plusses:
It is neat and tidy. In fact I would go further, it is incredibly neat and tidy.
It would definitely bring an end to lock ups on kisses and re-fuels.
It does look a whole load more professional.

Minuses
The knot in the end cap takes up some space and therefore the amount of engagement of the rod is less than normal. I am not sure if this will be a problem or not, but Wufer's suggestion of the end caps that are purpose made for this way of knotting seems to resolve this issue by not having the "eye" on the end caps, and therefore it creates more space for the knots. Jury out on this point.
It is fiddly getting the shockcord into the end cap. I found a plastic coated wire, the sort of thing that you find wrapping up the wires on your new PC, invaluable for pulling the shockcord through.

As you say purpose made fittings are better, one thing we were after was to move the bridles and elastics in from the extreme ends to reduce wear during tip stands etc on hard surfaces, by slightly extending the fitting length and fitting the knots in from the end means the sticks can not come in contact with the shock cord at the knots and adjustments are easier, easeing the knots out of the fittings and adjusting is not difficult although with 3mm and 4mm shock cord used it does not need adjusting too often.
The pic linked shows an upright fitting at the LE from the rear, all the other fittings are the same.
