I'm using the vortex venom. I had one instance this spring where the dot washed out my lens early morn. I'm pretty sure it was caused by dew collecting on the lens and me not getting it off properly. I tried just wiping it with my soft gloves but the material wouldn't absorb the water and just smudged it around. That's the Only problem I've had with it. I was a bead shooter as well up until last year with the purchase of a new 20 and the vortex sight. I didn't like it at 1st but I'm finding target acquisition pretty easy and i don't have to worry about aligning the bead on the rib properly. Just put the dot on target and squeeze the trigger.
