My only comment is to be careful if you are using a battery powered drill for twisting the legs. Once the batteries start to go, they go quickly, and if you only use time of twist as your guide, you can end up with two legs that have a fairly different number of twists. Depending on the amount of difference, they won't furl as well. For that reason, I prefer to use length of reduction, including amount of tension on each leg, to keep track of my twisting.
