I would think that the wind resistance would be better, but have no data to

You would probably get some fatigue of the plastic - translating into tears.
Don't know how much.

This I think could really work. Especially in a climate a little warmer
than ours. We think roll-up sides get a little too much cold air
infiltration for effective winter growing, but you are south of us quite a
bit. We have planted cold crops in late June under remay for shade, and
they did really well.
