>>333096I'm growing some right now and pic related is what I have.
It works but the sticks on the far left and far right are leaning inward. Also, once they're done expanding vertically, they'll try doing it horizontally, keep that in mind if you have other plants next to the peas (or you could just cut the new tendrils but I dislike doing that).
Otherwise I like the "roof" thing on B.
