My process is a lot like 94Bullit's, except that I tend to process my trees in the woods. I drop them, winch whatever logs I can reach from one set-up out to the side of the trail, and cut them up. Cut most of the way through, then roll them. If I see an opportunity to cut all the way through on the first cut (bend in log, or propped up on something) I'll do it then - makes the rolling easier.
I have a log grapple, and tried lifting them and cutting them in the air, but came to the conclusion that when working alone all the climbing on and off, maneuvering the log into position it was taking more time than just cutting them on the ground. If I'm cutting with another person or two, then lifting with the grapple to cut starts to make more sense.
I agree that the LogRite Cant Hooks and Peaveys are about the best thing there is out there. I had a wood-handled Northern Tool cant hook that was AWFUL. Wood handle was poorly made (grain was not continuous along the shaft) and the hook would not grab worth a darn (I tried grinding and reshaping the point: it helped a little, but not enough to make the tool useful). It was so poorly designed that it was dangerous. After only about 2 dozen used on moderate-sized logs (mostly 8" diameter or less) the tip broke off. It was a welded-on tip, and the weld was of poor quality. Tried a LogRite Peavey and have loved it since the day I got it.
