I think a few guys on here need to lighten up a bit. I have shoot many broadheads. I have also used Slick tricks. They are hands down the most accurate fixed blade head I have ever shot and I have never had any problem with deflection. One guy posts something negative about a head and suddenly its a bad product. If I boycotted every broadhead that I have heard at least one negative report about I would have to hunt with field tips. Here is a brief sample of what I mean.
Muzzys--------------------Don' t fly well and or group poorly
Rocket Ultimate steel----Blades fall out on hard impact
Rocket Steelheads-------blades are dull and the blades bend too easy.
Spitfires-------------------Penetrate poorly. Don' t open fast enough.
Snypers-------------------Tip curls too easy. Not rugged enough
Steelforce-----------------Long main blade too weak. Will snap off or bend too easy.
Magnus 2 blade-----------Tips can curl on impact. Don' t spin true out of the box.
Magnus Snuffer-----------Not glued to screw in adapter very well. Don' t spin true.
Thunderheads-------------Rear O-ring gets smashed out of alignment.
G5 Montecs----------------Dull as a fence post. Hard to sharpen.
Razorbacks----------------Bleeder blades fall out on impact
In general of course all 2 blade heads wind plane and leave poor blood trails and all expandables penetrate poorly while 4 blade heads don' t group well.

I could go on and on but you get my point. And please, I' m not saying that there is any validity to this list of complaints. These are simply a small example of online gripes I have heard about broadheads. Bottem line, you name the head and I will give you at least one complaint that I have heard about it.
