I used the sleeving on my TruePower 430 without problem. I too used a Molex removal tool (much easier), but you're still going to need to flatten some of the pins. Why?
Well, think about the TruePower. You have 3 Molex connectors on one line. If you remove all three and try to slide it over the middle ones, they tend to face the wrong direction and catch on the sleeving. Thus, flatten them after you remove them with the molex tool and then bend them back out when ready to reattach. The end one doesn't suffer from this problem.
I sleeved all but two lines because you can't really get it over the connectors. Also, for those with floppy connectors on the end, a little larger heatshrink fits but shrinks down to the same diameter as the sleeving. Thus, to keep it from accidently sliding (not completely tight), I used red zipties on the back part of those heatshrink areas where the sleeving comes into it (keeps them both from moving, and red matched the red heatshrink I used, which matches the one line that comes sleeved from Antec already).
It takes some time, but it's VERY nice when done.
I also did all the case fans.
