Hey everyone. I just wanted to pose a question to y'all. In many of the IDPA and USPSA matches i've been in i've seen guys with a pieces of tape on the lens to obscure the vision of the non dominant eye. Do any of y'all do this and what are its advantages. I imagine it has something to do with acquiring the front sight faster. But i'd like to hear what y'all in TFF land have to say on this.
