Thanks for the replies.

I'll wrap all of the 5x5 bales this morning. This grass/alfalfa hay is too good to take a chance  on mold.

I started out rolling the driest windrows up in 5x6 bales but switched to 5x5 when moisture meter started reading over 20% so I could go either way (wrap or net only). Seems like a useful tool.

Here in sw wi we hardly ever get the weather to get hay under 15-16% before a rain.

My 569 has the "soft core" option which is why the center 24" looks a bit different than the rest of the bale.
