RE: Copper John,TruGlo,Cobra or other sight?
i used to have a copper john on my old bow and loved it. i bought a new bow this year and originally i had a cobra sidewinder on it. but i couldn't get the elevation set screw tight enough and ended up ruining the sight by trying to crank the screw down as tight as i couldcobra said there wasn't anything they could do. so i junked the cobra sight and bought a montana black gold skylight and it is the brightest sight i have seen so far. the sidewinder is second . i would suggest comparing all the sights you like head to head in a darker than under flourescent light setting.
