I have used mechanicals (RocketAeroheads Hammerhead)in the past and have had a mixed bag of results. The first buck I shot was about 20 yds. broadside, shot him a little far back. However it looked as if you poured blood from a 5 gallon bucket. I also shot a big 8 point with another Hammerhead, about 25 yds. I had good shot placement, but didn't get pass through. So I am not sure what to think. But I am going to trya fixed blade this year though (SabreTitanium). I'll let ya'll know how it works out.
