I'm looking at the new Zeiss LRP S5; to use the 140 MOA travel, you're going to need almost a 70MOA base. Two options currently have my attention the ERATAC adjustable and the SPUHR 41808 (

I'd prefer the SPUHR as that's what I'm running with my TT on SRS and ATACR on HTI (the 38mm/1.49" high and 44.4MOA/13MRAD cant models in 34mm size); however that linked SPUHR 41808 is 1.73" tall (44mm), which is 6mm or 0.24" taller than the 38mm Spuhr I have on there now. So, I'm wondering if any of you have actually used this exact Spuhr on an SRS or HTI and if it was too high to get a good cheek weld and sight picture.
(Holding off on the ERATAC now because I don't want to adjust it, just set it up at approximately a 100 yard zero to get as far as I can with 338LM and 375CT and 50BMG before attaching the Charlie - to me that's one of the big advantages of the new Zeiss, its massive elevation travel.)
