I use a 20" bolt with 100gr Rage mechanical broad heads. Rage has a 2" cut and are badass. They're expensive, about $35.00 for 3, so I get'em with my Cabela's points. If I run out, I just use a 1gr 3 blade Muzzy. Get'ya some lighted knocks. They're really cool. I use Tracers.
Other than that, I don't know much about cross bows. I've only had mine for 2 seasons.
