Please review this screenshot. The math shows what you were talking about. I used oring ID sizes, not actual pin diameters (too lazy to measure or look them up); it should be close enough for discussion purposes. If the reactivity couldn't be adjusted out with shims and/or a different top on/off oring (quad vs. urethane, etc.) for the RT-head/ULT-shaft scenario, surely it could be for an 005-head/001-shaft. It's almost identical to a standard RT.

Don't get me wrong. The ULT is a great product. I am just curious to its history as of late, so I wanted to discuss it. I was hoping to see what prototypes failed and why.
