I'm looking for a statement or focal point evergreen for my back yard against a lengthy fence. Needs to be Zone 6 friendly, will be in full sun and has irrigation. There is an American Cranberry, and Korean Fir as anchors on this stretch and then two boxwood in the bed, and will also have two blue arrow junipers. I am looking for height, privacy and to soften up a fence line.

I want something unique (I have a weeping spruce already in the yard in another area and I love it - can't justify a second but that's an idea of what I'm looking for) and with different color, structure and texture than the boxwood and junipers and am considering Alaskan Green Arrow, Japanese Umbrella Pine, Stowe Pillar White Pine, Slender Hinoki Cypress, Bennetts Fastigiate, Green Hinoki Cypress, Pinus Flexilis, Yukon Blue White Spruce or similar. I don't like yews, or trees that are messy with lots of fruit or droppings and don't want anything that requires much in the way of pruning or care other than fertilizing. I'd like to be mindful of size, so am looking at maybe 8-20ft high and 3-10 week wide. What am I missing for consideration? Any thoughts on the above and how they fare in the north shore of Massachusetts?

(also, the fencing lines running parallel to this bed have Degroots Spire, so while I like them, I am not considering additional arborvitae).
