RE: How much draw weight is too heavy.
Overbowed will be measured in time, with arthritis, aching joints, and a doctor perscribed crossbow permit.
To me, overbowed is when you are using a bow that is substantially more than what is needed to accomplish your objectives.
My 57# Ultra II is equal to my 1989 PSE Fireflight at 75 pounds. If my PSE Fireflight was more than enough to adequately harvest a deer in 1989, then do I need to shoot an Ultra II at 75#'s-even if it's easier?
A person will always shoot their best with the lowest poundage, with the least amount of stress to their body. That poundage range is also most condusive to long term physical maintenance.
I've seen torn rotator cuffs, arthritis, sore necks, and displaced muscles do to excess poundage. It's not for me.
