But seriously,
I have absolutely nothing agaist Fixed Blade Heads, But I think Alot of People shy away from Mechincals based on hear say, when Someone loses a deer they are looking to point the finger...must have been those darn Mechanicals... It couldnt have been my shot placement or a poor Tracking job or as we all know in bow hunting one of those instances where everything was perfect be the end result wasnt.

I've only Ever Lost one Deer and it was with a Thunderhead, but It wasnt the broadheads fault, I could have been shooting a Field tip and if the arrow went where it was suppose too, He'd be deed. Luckily Ole boy lived thru it.

Personally I'm Blaming the Horse Shoe up that 140s Arse. Not only Did he take an arrow from me and live, 1 week later he was at 10yds from my hunting partner and as he drew on him, his release exploded into Pieces.

Basically if you know your set up and select your broadhead accordingly, you can be very successful with either type of head.
