Brandon- I think they are pretty good trees and out in the open. I doubt Ill ever put a pump on them as few as they are so thats why I think I may do that. Be fun to see what they do. I was reading a research paper from the 70's and they were advocating up to 80 taps and claiming up to 20 max inches of vac. Im not a gravity man whatsoever but I consider that a fun experiment to see what they do. Plus its quick and easy and more sap. Well see what happens. Theres another 130 tap spot I could do the same thing with but its just a gentle slope with them all together. That would be just several normally loaded lats but the hedgerow one is something that we could see what happens on. They said the vac levels on the natural arent consistent like a pump, different at differant points depending on how good the run etc but it all helps what the heck. Theron
