I'll try to answer the Qs as best I can.
The chenille vs. wool issue is just personal preference. I used to use wool and I plan to try it again (not necessarily with this method), but as TOGWT suspected, the chenille allows better water flow from the inside out. Other reasons include the ease of maintaining the chenille ones (just toss them in the washer and dryer) and the simple fact that I have a bunch of them (I can go through a LOT of mitts during each wash). Heh heh, this is extreme enough without five or seven lambswool mitts getting handwashed and hung up to dry
MF mitts- I like them VERY much except for the way some kinds of dirt seem to really stick to them. They just don't rinse clean enough for me. Note the optional step of rewashing with a MF mitt- I don't mind using them once I've cleared any major contamination from the surface. As to the length of knap, that's just another personal preference issue. *I* like having long knap that better allows me to just barely contact the surface of the paint.
6cyl's_of_fury- I haven't tried QEW yet, though Lynn and I have discussed how it might be a good idea for the rust-prone Jag. Heh heh, if I ever DO try it, I'll probably come up with some extreme version of how to use THAT too. I sympathize with your situation; I'm truly spoiled by comparison. I go through a *LOT* of water (high volume, boosted pressure, etc.). You wouldn't believe my water bill
Jesstzn- That's a good point, and one I sorta glossed over. I've gone both ways, and settled on brass disconnects due to their durability. I have plastic shutoffs right before them, and that was the area where I used to hit the wheelwell lips (the part of the hose just past my hand). I stay well back when rinsing the "regular" panels, and when I work in the wheelwells, etc. (up close) I attach plastic hose ends to the disconnects. Not as safe as your approach, but I'm pretty careful and I've gotten used to how I have to do it.
But yeah, most people might be better off with all plastic fittings. Too bad they don't hold up (I go through 6-8 plastic shutoffs each year). Gotta watch they don't launch the nozzle when they go bad!
Gonzo- Heh heh, very funny

Nah, it's not easier on an Audi

and I'm running out of paint on the Jag. But on the beaters (or even Accumulatorette's A8), yeah, it *IS* easier; remember, on those I even use BHBs!
percynjpn- Yeah, they're a sweet pair of cars. They're pretty special, in different ways, and true "keepers".
andriver- Yeah, concise for a long-winded guy like me
