One thing I'll warm about for drop aways (like the QAD or ripcord) is that I have had them freeze on me in rain/snow. The moisture builds up side of them while locked in the up position and they dont drop.
Good point. My two hunting partners had this happen to them this year in MT - QAD and Ripcord... I was fine with my Hamskea. Fortunately they noticed it was happening and didn't have a failure shooting at an animal.
