I have 4 Schons with the stainless joint. I have a 2x6 led light at home with egg crate diffusers, and shoot two leagues, one with Predator style arena lights and one with what looks to be a figure 8 style light. I don't like the figure 8 style light, but on to the stainless joint, I'm 6'2" and have never noticed a glare on the stainless joint.
As to shafts, weight, diameter, and balance are most important, also a reasonably low deflection, but I don't feel you have to have the least as as long as it is somewhat low, just get used to it. The joint match, whether it has one ring two rings or matches means nothing to me.
