I looked at buying square stock to laminate from ACS. It costs a good bit more than solid, because you do pay for the sawdust losses they make. With a thin kerf blade cutting capstrip, I lost about 1” on a 5” board to sawdust. Smells good at least. I think laminated spars are great. You still have to find quality wood. I will say out of the blue, one of the Home Depot’s started carrying doug fir 4x4 posts that is close. I keep checking the pile for the day the right one is in there.
