While I was considered a local Bow Guru....I am completely lost now that I have been forced to horizontal archery.

That said, I have a 200# Horton Hunter from Cabelas. It shoots what I would call decent. The thumbhole needs augered out some to fit my big paw. I am shooting 3" to 8" groups up to 50yds. Not great I know. I could make arrows rattle at those distances with my Hoyts.

My question is this...I currently am using 22" Carbons w/100gr heads and a local shop told me to go with 20" and a 125gr head. Now when I try to apply vertical archery theories to horizontal archery arrow selection it simply doesn't fit. Grs/lb is out the window. Is it all just pure spine? If so the 20" version would be stiffer I assume.

Any help with arrow/bolt selection theories and ANY tip on tuning and shooting more accurately would be helpful. Remember I am a former prostaff shooter and full fledged, card carrying member ofarchery tinkerers annonymous so I need some help getting started tweaking on this thing.

Thanks in Advance for your help

Dave
