I had contact issues and mine were from the nock point being to high actaully. I raised the rest a click and no more issues. Mine 1/8th inch above square. Also, i had issues dropping my arm on the shot which created some contact also.

do a search and you will find a few posts in here with my issues. Even a picture of the contact I had. Its a great rest, just hot or miss on some bows. I had a heck of a time getting mine perfect. I still think its the best drop away, but it just takes time to get perfect, espically withblazers
