Had an 20+ year old pergola falling apart on my back porch. Designed and built this 16x12' guy over the course of 2 days.
I built the whole thing using and impact driver, and a miter saw for cuts. I used joist hangers for the cross pieces as well.
It's designed to handle up to 1 ft of snow without sagging, which would be a record for this part of NM. So far seems to be holding up.
Really happy with how it turned out.
I used some of both. Just depenended on which was right for the particular joint.
Nice part is both have engineered ratings.
