Just a thought since it worked great for me. 2004 season I missed a real hog due to not seeing thru the peep in low light so the fallowing spring The Lone Wolf talked me into ripping off the peep and using a kisser and WOW was it the best thing Ive ever done. I started about May and I shoot 2 to 4 times a week and that seemed to be enought make using a kisser habit by the time october hit. I made a few great shots and had no problems doing so this past season.
