Have been installing the WSD springs on customers pistols for a while, not sure I agree with their logic on reversed rod either. I thought about full size full length,,, but because the rod must move I think I will relieve most of the rod to cut down on drag. May leave a hub (support point) in the center to prevent flex like that found on the 10mm and .45 rods. In regards to the area I am talking about I have founded some rods that where so chewed up that all the plating was gone and a ring had been formed in the rod.
