I have a Mathews ultra max and stopped using peeps altogether. I usually just hunt woods and swamps so my shots are only 30 yards or less and I only have 1 pin on the bow. I put a kisser button on my set up and practiced getting the form the same every time. The string hits my nose and the kissersits in the end of my mouth. I find that it is accurate for hunting purposes at short ranges. If I can't see the pin then I know it is time to get down and try another day.
