Yes, I figured those on the flood plain had to be Reds but thought perhaps those on the hill were sugars because on the Hudson Valley River Intervals, typically the Reds will prevail on the flood plain almost exclusively and then as you have any rising glacial sluff, even just a few vertical feet off the flood plain, the sugars will prevail (albeit some reds will propagate there as well ). So I was hoping those were sugars in the big cluster up slope. But no big deal, just a bit more work for you, same exact great taste. Don't let anybody get racist on you with quality/taste on reds VS sugars.

Getting at least some vacuum on the Reds will be important. IMO the ones on the slope should be easy. I have no experience pumping up hill so can't speak for the ones down by the bog. I imagine a good pump will work well on those but not sure.

I have a cluster of 21 Reds that I tap in Connecticut and the situation is nice because they are up on the flat (wetter and poorly drained ) of a ridge side. With a steep drop down to my barrel. The first year I tapped them they were on drops to buckets and many of them did not run well at all and some not at all. The next year I did 5/16 tubing on them and they ran off of that alone and generated a little natural gravity and so then I put a solar 12 volt pump on them and they ran so well I was overflowing my barrel in one day/night.

So Reds want/need some vacuum and the more the better as you may well know.

If you're going to be using a decent pump, then don't worry so much about the natural gravity you are going to generate. Either way you do the gravity run, the gravity vacuum generated, is not going to blow the collection barrel up. But do take advantage of it as best you can and try to get everything down sloping at least a tad. Drops included.

As we said the steeper and longer that final run to the barrel is the better, but simply put that is the haymaker in gravity tubing, even though hydro dynamics in Vaccuum tubing is VERY complicated.
