I am going to be ordering an Aimpoint H1 with LaRue mount directly from LaRue later this week. I have a few questions. The 2moa and 4moa are the same price. Will the 2moa make for slower target acquisition at close range or is it such a small difference I won't notice? Someday I may add a magnifier so I'm thinking the 2moa would be better for that. The next question has to do with astigmatism. I have a astigmatism but wear contacts to correct it. Will that reduce the blurry dot and is one size dot better for the astigmatism? Final question is which mount. I have no experience with co witnessing. I understand this is more of a personal preference but am wondering if there is some sort of guideline for choosing absolute over lower 1/3? Thanks in advance for any help.
