I have steel 108s and a 50lb wing is just fine. I have an oxycheq 50lb wing - great wing. When I took my cave class - my instructor, my wife, and I all had oxycheq 50lb wings on - we had them sitting on a bench - and turned around and saw all three of them lined up. Quote my instructor - "Looks like an ad for Oxycheq".
Once I get an aluminum backplate (have stainless steel from my singles days) the 50lb wing should be plenty for double 108s + a stage.
