I've got roots showing all over the place which is a good sign. I was going to float them all out at day 14 just to see any differences but I didn't end up mixing my soil yet so I'll do it this weekend as I want to replace a couple of other plants with some of these since they look so much healthier. It sure is great to have choices!
One interesting observation was in the health of the clones after potting in soil. I kept the best two clones from each of two different strains, and in both cases I had one aloe dunked and one not representing the best from the group.
After being potted up in soil for about a week or so, the two
 non-aloe dunked plants are larger and look healthier, wider leaves, etc. Not what I was expecting.
Still, it's only 4 plants but so far there's no clear advantage to an aloe dunk either for faster or healthier rooting, nor for healthy growth thereafter, and one could argue it's better off going without.
