yea it seems like that would put more air to more boards. Just not sure on how high you would want to go, three feet was as narrow as I would go for stacking, and this was stack of 12" wide stock I did however do some single stacks of wider stock wide stuff, I mean wide stuff like 15" to over 20" stuff,, and this was mainly due to not having that many, and wanting to keep weight on them, so I just stacked them up. ended up moving again and again, so this lends itself to that double handling crap that I just really am not a fan. The 42" width stack just worked well for me, it was stable, it worked out well for most all rough sawn width dimensions, in that tallying was made easier, (for me) ect. it really don't matter, just what works for you.
