Good for you @canna-amber!
Nice to meet you.
I know your location...grew up across the lake and am very familiar with lake effect snow and cold temps.
I agree with all your observations.
I think your High bushes (if you can keep wintering them) will produce for you in their 3rd year. Seems to take about 5 before they can pump out pounds...and you're definitely hedging your bets with variety in the cultivars.
