Nick,
This is what I did (see picture) basically just pushed some needle felt media through and put a little glue each end.
Walshd,
I also used to have trouble getting the depower rope back through, what I have used that works really well is a 20cm (ish) long piece of sail repair tape and just roll one end around the last 5cm of rope like you would a cigey paper and use the remainder to pull the rope through. This stuff stick's like anything and you can't stretch and break like normal tape.
LouD,
It's Rev. Some of the early bars are slightly different.
TOAD,
My harness has a habit of steeling my DD's, something to do with the Warrior harness's spreader bar. I do normally have one on, but like BrisKites said you don't need one unless it's really gusty and even then only on the beach when your kite could fall back and unhook.
Cheers
Grant.
