Bamboo Phyllostachys Bambusoides(Madake) or P. Edulis (Moso)

I can't decide between Phyllostachys Bambusoides or P. Edulis as a timber bamboo for my place. The place is zone 7b more inland on a island on the west coast of Canada with shallow clay soil over limestone. Growing up I always wanted a bamboo forest-fort never could have because other people's bamboo-phobia so the biggest bamboo possible. I also want the culms to be strong enough to build coops, small barns, greenhouses, sheds and I can't find out which one has the stronger culms
I already decided on P. Vivax for a fast growing green manure, fodder, mulch, shoots, ect (any one know of a faster growing bamboo for my area?)

P. Bambusoides Madake similar to vivax but slower growing with stronger culms, but faster growing then Moso, primary Japanese building bamboo
Max Height 72' (West Coast Estimate 40' Feet)
* Max Culm Dia 6"
* Evergreen to -15C
* USDA Zone 7, Root Hardy to Zone 6
* Sun or Shade
* Running Bamboo

P. Edulis Moso largest temperate bamboo, a very good thing, some websites say that it's slow grower others say it is fast, used for building, wider culms then Madake
Max Height 72' (West Coast Estimate 40' Feet)
* Max Culm Dia 6"
* Evergreen to -15C
* USDA Zone 7, Root Hardy to Zone 6
* Sun or Shade
* Running Bamboo

Oh also I don't want to babysit sit any bamboo thro the winter

Your location has cool summers which limits the invasiveness of Phyllostachys running bamboo, in cool summer climates such as the British isles, they grow like a clumping bamboo, spreading only a foot or two each year. Of the 2 species you mentioned, bambusoides would be the better choice as edulis is a bit more finicky, preferring warm humid summers such as they get in the SE US. Another species that would be more likely to thrive in your cool summer climate is the P. nigra group, of which P. nigra henonis and P. nigra bory get 40 feet high. They are native to higher elevation regions in China than are bambusoides/edulis, and more tolerant of late frosts and cooler growing conditions.
