Been cutting a lot of PT wood in the shop the last few months and you're right, some is so wet that you have to have a towel handy when cutting it.
Often the past year or so an entire pallet of HD tubafours is dripping wet 'peel cores' from the plywood mills ... this stuff does not readily accept the treatment and warps like crazy after it dries to around 30% ... an entirely useless product, sold at a premium price to those who don't care, or know the difference.
peeler cores are almost always juvenile wood, it takes about 15 years of growth before SYP starts producing strong stable wood, that's why they get so crazy warped up.
not at all, heartwood in pine is another issue and may take many years to form, most southern pine is cut(now) before it ever gets to the heartwood stage in its life.
The young tree wood or juvenile wood stage in a tree may be passed in as little as an inch in diameter or it may last to six or eight inches in diameter in a plantation pine. Depends entirely on the growing conditions.

That's the main reason I don't do that style of line fence. I haven't seen any good stock in town anywhere and half the new line fences of the peeler style are warped as hell, up to 3" off true in any given green peeler.
I suggested that another client get her own "cherrytone" landscaping peelers because I would have to charge her for the winnowing process at an hourly rate. Her husband has a pickup and they bought the first batch, so the suggestion wasn't as far out of line as it may have sounded.
There is far too much crap wood being sold everywhere nowadays. I asked the guys at both local lumberyards why they didn't have a slightly better grade of PT lumber. He said that people wouldn't pay for it. I told him that my clients and I had discussed it and all would be happy to pay up to 50% extra to get lumber which was sound, which wouldn't warp as it dried, and was properly dried after treatment. They suggested my telling it to the owners, who are seldome around. Oh well...

That's what I did when I built my deck and after the PT decking dried out, I have too big a gap for my tastes. If I had it to do over, I would have butted the PT boards and let the gap for drainage develop on it's own as the wood dried out. For this reason I would not go for the Kreg system, not to mention a 100 bucks is too much for this tool, particularly if you are not in the deck business. I have no complaints about the standard screw from the top, but the EB-TY system looks good if I wanted to eliminate visible fasteners.
That's what I thought when I built my deck, and used a 16d nail as a spacer. The PT was not sopping wet, it was fairly dry for PT stuff, and damn, I wish I had ignored my instinct. Of course, had I done that, the damn stuff certainly would not have shrink, but expanded. Instinct is hard to ignore....
