I wanted to say thanks to everyone here. I dont have a pro shop where I live so Im thankful for getting a lot of help on this board. I'm installing a BG Vengeance sight on my element. Ive never used a sight with so much adjustibility options. I'm familiar with pin setup and 2nd and third axis setups. What I'm unsure of is the main vertical and horizontal adjustment options. Are these adjustments used to get me lined up with my peep? Or should my vengeance be sitting off my riser a certtain way? (i.e. low to arrow shelf, etc)
