Are you saying the 14 requires more OUT travel (counter clockwise) to get it to focus than the 9mm does?
Once I get some clear skies, I'll be able to test this myself (except the 9x100 ES hasn't been available for quite a while), but I'm curious what you've found. Because if the 9 and 14 are like the Ethos 8 and 13. the 9 should require a lot of counter-clockwise movement of the HRCC to get it to focus after the 14 is in focus. If it requires clockwise motion to get it to focus, then the 9 and 14 x 100 are constructed differently than the Ethos. Yet, Xrays show them identical in configuration to the equivalent Ethos.

Weather permitting. I'll confirm or deny this tonight. I'll take exact measurement on in focus and out focus requirements of all 3 relative to each other.
Edit: Actually now that you mention it. I turned the top LEFT when I moved from the 14mm to the 9mm to get focus. But, it was not much. Couple of millimeters over all. I think.
