SB: No-Pin System/Bale Orientation Refresher



Greetings, everybody.
 
In the contemporary history of bale walls, first there was the internal rebar pinning system.  This then gave way to external pinning, especially in the cold climates where metal in the wall was an invitation for moisture.  I have heard numerous references now to walls being laid up without any pinning structure, but have not found details on these systems.  Can anyone elaborate?  Furthermore, how might this relate to my situation: Nonloadbearing bale-wrap walls, pinned by vertical 2x's laid on flat on the interior and exterior fixed to the floor bale track and soffit or top plate and tied together every other course w/ heavy twine, with a vented clapboard rainscreen attached to the exterior pins.  I'm assuming here that pinning makes sense, in that it serves more than one purpose...
 
Also, in reevaluating whether to stack walls w/ bales on end or on flat for a non-loadbearing bale-wrap wall, I was trying to weigh pros and cons.  Can folks add to this list?  I was unable to come up w/ much more on a listserv archive search or through books.  It seems that the difference isn't extreme (again, for a non-loadbearing wall).
 
On-edge pros: better insulative qualities due to strand orientation, fewer bales needed; Cons: difficult to modify, particularly to shorten vertically to meet with second-story tracks or other horizontal plane framing interruptions, harder to earthen plaster w/o wire mesh (can it be done anyway?)
 
Finally, I'm throwing out another call for a lead on bale sources in NE US/ SW Que. 
 
Thanks for your help and your recommendations.
 
In Peace,
