Since it snows where you live I would not go with a 1/2” hardware cloth top because it’s really hard to get it to not build up on the top. The 1” allows the snow to fall through better and it’s easier to knock off. We just got a foot and half of snow and I have a little section of 1/2” hardware cloth on the top (just because it was a scrap piece) and the rest is the 1”. The snow got through the 1” but the 1/2” I couldn’t get any to fall through it even with hitting it with the back side of a rake lol.
Here’s a picture of how I made supports in my run for the hardware cloth top. I attached it with screws and washers.
