Pat, on your very fine bird-bead relationship thread, I note that you use both tape and a fiber-optic site. Why both, please? I thought if you were successful using the fiber-optic, you could keep both eyes open to cure cross firing. I, too, am a one-eyed shooter. Tried the fiber-optic but my eye wanted to come back to that bright dot, thus leaving the target. Tried the tape but my eye works around the tape unless I tape all the way across the lens. So, I just squint. Also, do you hold a high gun or on or below the roof? And what hold points do you use? Thanks. Guy Coates
