Good morning. I have been rifle/muzzleloader for whitetail for a few years and I am wanting to start bow hunting next season. I have an inherited bow from the early 90s, a Jennings Carbon Extreme XLR with 80# draw weight. With that in mind, I have a few questions: 1. I don't want to spend a ton of money starting out, but has the technology improved enough where it would be a significant improvement to buy a newer used bow or an entry level new bow? The bow I have seems pretty heavy and I think the let-off is either 55% or 65%. The draw length seems to be correct for me. 2. The bow I have (the Carbon Extreme) needs a new string. The bow says it uses a "AMO Compound Bow String Length" of 60.5". I can find a lot of info on AMO string length to actual string length for recurve bows, but not for compound bows. Can anyone help me identify what size length I would need?
