Got a great deal on this Mathews Ultra Max SoloCam. Wanted to limit my investment for the first year, get my Archery cert. taken care of, then get a nicer bow next year. Got some arrows cut at Sportsmans on 130 in Bordentown. Do I need a stabilizer? What about silencers for the strings? Also any recommendations on broad heads (fixed or mechanical, 3 blade or 2?) would be greatly appreciated.
