Hi there Sea Hair,
I haven't had the best experience with #2 Yellow Pine and warping. Last year I used it to laminate the 20' keel on my cutter. Even with 6 layers of 2x8s laminated with epoxy, the keel piece had noticeably warped by the end of the summer! I ended up have to reshape the entire thing with a power planer.

I went with rift sawn white oak purchased from a sawmill for about 1.50 bf from there on out and it the tiny amount more I paid for it has been worth it!
