[M.T. Pockets]

Thanks for the input guys, I appreciate drawing on others experience. I think I'll just upgrade to 4x4's from the start. I've been looking at the metal brackets available that hold the legs in place and have spaces for 2x6 cross beams for the floor deck. I think this would firm it up quite a bit.

I've considered the portable stands and may get one eventually. I'm in northern MN and I own some property and was thinking of one good permanent stand.
