I'm still waiting on Stage 3, so it's hard to know exactly how it would be used, but I know I want 15mm rods up top. I suppose it will depend on what I'm doing.
I don't have any other 19mm accessories, so this makes no sense for me, but would like 15mm top rod/handle solution.
Really liked how you tied it in with the handle and kept it low profile.
Personally it would work best for me with 15mm ltw, but 15mm studio could work as well.
