How does Blaser glass & durability compare to the ZP8? I'm in the market and have previously owned the 1-8x ZP8. My main concern is the reticle and capped elevation. With that said, a 200yd zero on an AR would still get done everything I'd ever need. Trying to decide between the k16i, z8i, blaser, or some sort of mag/red-dot combo.
