Looking to upgrade my 5” bird on bow . Linked to a Terrova. Looking for suggestions on a solid used bird graph probably 9” or 10” . Mainly for spider rigging. Im NOT very computer savvy . Wanted to get y’all’s thoughts on live scope vs 360 vs 2d/Di upfront for spider rigging? I only have experience with 2D/DI/SI . We have a helix 9 SI DI on console we use for scouting and pulling cranks . TIA !
