I have often toyed with the idea myself of gettin rid of mine however i drilled the one i have out a bit more and there seems to be an adequate amount of light coming through it. I find that when i lose the light i am right around shooting time anyways so it keeps me honest. I do not shoot enough or have good enough form and consistency to go without it i think.It has cost me shots b4 yes but those were probably shots i shouldn't have been taking in the first place anyways.
