Okay, I'm using all 16 shafts of my new-to-me AVL for the first time, and I have a fairly wide warp (40"). I'm starting to see why a power assist might be helpful. I see that AVL offers an electrical and a compressed air powered assist. The air is certainly cheaper. Does anybody have any thoughts on these two options? Pros and Cons? Love this loom, but this is hard work.
