for what its worth, I got a set of ball-end allen keys and can swap the DV on and off in ~10-15 minutes on ramps, its a lot quicker (for me) than using the extensions and taking off the wheel.
You won't be able to see a lot of what you are doing, so looking at a picture of the area as you feel around will help a lot. Really depends on how familiar you are with working on cars. Also, don't remove/install a DV when the car is hot. Not only does it suck to do, but you can easily overtighten the fasteners. Go ahead and take it off while it's hot, but let the car cool off before reinstalling.
