Hello i am new on to the forum so I apologize if this is in the wrong place or wrong format. I recently went to a shop and got new switch weights for a Matthews vertix that I would like to setup for a 75 lb 29" draw. The markings on the top cam switch weight are SW 75#, D, 85.A and the on the bottom cam SW 70#, D, 85.B (I shoot left handed). I was not smart enough to check his work before I left but was wondering: 1. Did the pro give me a 70 lb and 75 lb or am I the one missing something? 2. Are they put on the correct cam? Thanks!
