Might look at one of the Primary Arms micro prism sights, not affected by astigmatism. Just put one on my Traditions and haven't hunted with it yet, but pretty cool sight.
I found this to be true. Hunted with mine last year and harvested a small bull as well. No flaring or glare. Also before season while I was familiarizing myself with the setup I found that i was able to consistently drill a 8" plate at 200 yards by lining up the plate in the middle of the bottom of the chevron.
That would be amazing! I use to feel comfortable and get a good group with the X-150 out to 175 yards with iron sights on paper... Now my eyes are garbage... So I have to sight it in at 50 yards...
