On the Kipping, I knew that I had read somewhere on here that the Kip was a sub so I checked through some posts. In "Fitness training" under the topic "Pullup Technique" this post came up:

Also, I burned out my nervous system doing negatives, so mix it up. I don't see an issue with using a pull-up machine, but you don't get as good a workout as when you are free-floating from the bar.
As suggested on simplefit, you should consider doing body rows , possibly with rings as you build it... mix it up.
This is where I got the idea that it's a sub. I got the ratio wrong though (2:1vs3:1). It seems to me from the vids I've seen on crossfit it would be equally hard as Zorg mentioned as it uses more overall body work and seems to be more cardio. Anyway thought I'd throw that in there but I'm all for counting 1:1 whenever I can even do a Kipping Pullup if that is the common thought.
As for the Straight vs. Bent arm start that ianjb posted I tried that last night (although it was after a LOT of shovelling) and found this: I was able to get the 2/3 way up on the first time with my arms straight. Then my wife, God love her, pointed out that I had not fully extended my shoulders
despite my arms being straight. When I tried it with arms straight AND shoulders fully extended I could barely get started too. Looks like I have more work than I thought ahead of me
Back to the drawing board I guess.
