I did a set this Spring.
I would say the same thing that cj001f says, not the best binding to learn mounting on. However, if you are naturslly good at these sorts of things, and if you are really meticulous, and very careful with measuring, and you follow Lou's procedure to the letter, then you will likely be OK.
The problem with Dynafits is if the mount gets screwed up, then they can prerelease, or not release, as the relationship between toe and heel effects the alignment of the boot in the binding. If you screwed up a Fritschi, for example, the only real problem would be that your ski might be a little crooked on your foot.
Taps will be neccesary if your skis have any metal sheets in them.
I measured everything about three times before I drilled, and put aside a whole morning so I was not rushed.
cj001f, this is the only place I've seen the rental plates.
