ive always shot mechanicals ever since i started hunting. they have never failed on me knock on wood. Last year i shot two with the bow. I usually use rage two blade but tried G5 T3s i shot the first one with the g5 blew threw it and stuck in the ground a good six to eight inches but wasnt impressed with blood trail though it wasnt needed for the deer only ran fourty yards and dropped "heart shot:" so i went back to the rage two blade on the second hit it a little far back never the less the deer went a good eighty to one hundred and dropped, however decent blood trail i here alot of bad stuff about the rage two blade but i have never had any real issue with them other than when you put them in the quiver and they open they never seem to close tight without a new o ring
