From surfing a lot of threads on the subject, a lot of people seem to be using 2x6" for the stringers/beams in their walls.
How come the moon wall how-to along with the metolius reccomend 2x4"'s.

Metolius actually recommends 2x8 construction for all steep walls. Moon uses rough sawn 2x4 with a center support brace which halves the span. Rough sawn lumber available in the UK is also actual 2"x4" which is 25% stronger ( approximately).
I use 2x8 for all walls 30 degrees and steeper, 2x6 for walls 15 to 30, and 2x4 for vertical walls.

Aha! didn't spot the difference there.
I can get 2x4's for free, but not so much 2x6.. I'll build with the center supports to reduce the load on my existing roof construction.

If your building a Moonboard realize that standard 16" OC or 24" OC joist spacing will not work with the metric t nut pattern. For 2x4 or 2x6 go with joists at 0,20,36,60,76, and 96. If you use a mid span support or use 2x8's then you can get away with 4 joists at 0,34,62,96. (Side joists measured from outside, middle ones on center. )
