Being in approximately the same zone as you, I planted a rubromarginata division last summer which got a bit of leaf burn over last winter probably due to not enough time to establish, but this year it has made many new small culms, nothing close to what you have. Hopefully next year mine will be pushing 10ft like that. I'm still kind of impressed that you went from spindly 3ft culms to a grove in 1 year.
March 2010 with leaf burn.
June 2010, and still shooting now, but still everything under 4ft.

Why is that the tallest in your area?
I grow Phyllostachys Vivax and Phyllostachys pubescence which grow absurdly big here in the UK. The former grows 20ft from seed in 3 years! (sudden jump on the third only 3ft at 2 years). Pubescence is a bit slower getting started. Perhaps they are TOO BIG for your purpose?
Living in a zone 5b/6b limits me on the bamboo I can plant. From talking to bamboo growers the colder the climate the shorter the bamboo. P.rubromarginata just averages out to be the tallest.

Being in this zone it seems like moso does pretty well as single tarp protection is enough to prevent leaf burn here, but vivax gets top killed regardless of getting tarped.
