I agree, all pretty good advice ... however ... not every day is a rainy day ... so (if I were active) I would NOT be building my conditioning platform around "rainy days" ... but rather would just be prepared for them

In other words, because I feel the jenny is best, I would be using that every day I could, and would only switch to the mill on days I had to ... rather than only use the mill because "it might rain" someday. The weightpull harness and flirtpole also comprise my preferred keep. I personally would only use the mill on days I had to.

Don't get me wrong: I have a full mill keep too, that is pretty good, but I don't think it is as good as the main keep I have ... which has no millwork at all ... but plenty of jenny/pull/flirtpole work.
