I was shooting last night in my back yard, getting all sighted in (i just put new string on the bow) and the guy at the store said it shouldn' t effect my sights that much. He was wrong i was 5 feet low at 10 yards (yikes!!!) So i readjusted the sights and got shooting again. Than my rest becomes lose and the prongs move on me... I have no idea on how to set those guys in right and make sure all of them are alligned right. What should i do.... I think i might by a new rest but not sure if i should or not?
