I saw a picture of mark drury in a cabelas magazine that he is only pulling 53 pounds on his bow. I dont care if you are shooting a rage or a fixed blade, 53 pounds wont always pass completely through a deer. I shot the G5 tekans last year with my bowtech 82nd airborn. My set up was producing around 88 ft lbs of KE and I had one arrow not blow through and stick in the ground on a buck. If you shoot an expandable with a big cutting diameter it would be wise to have a set up producing a fair amount of KE. My wife is only pulling 53lbs but every deer she has shot the arrow has been a pass through. Im swithing her over to the rages this year to try out. If penetration becomes and issue she will switch back to fixed blades.
