Running talley lows and 42mm objectives with my EH6's which have the same drop as the EH8. Extra lows would work, too. What makes you think they wouldn't work?
I figured the raised cheek piece on the eh8 would get my cheek weld too high and not align with scope. My hunters edge with Lows is about perfect and it has no cheek piece at all. I'll likely give it a go. I want to try a manners. I've never owned one. I just like the looks and I want something other than a Mickey this go round.
