I shot without a peep for years.....I always touched the string to my nose and never had a problem with the string getting in the sight picture.....

I shoot a Shurz peep (sp) and have a zebra string......If my peep is not lined up I simply twist it around til it is.....When you draw, however the peep is aligned, it will stay that way.....they say you have to train the peep/string.....
