Have a tommy hogg 5 pin slider with a hogg wrap and .10 pins. I shoot both eyes open and love the precision of the .10 pins but age is catching up to me. The fiber optic pin is tiny and has become a little blurry when focusing on the target and not the pins. Switched to .19 pins and I can see again! Also ordered the spot hogg sight light off amazon. To cool. Makes the pins glow. Only for giggles and practice though because any electronics/ batteries on your bow or arrow is a no no here in CO
