What broadhead would you use if limited to one, why?

[Wudstix]

Yes, there are many good and great heads out there, pick your poison.  Good solid heads are all winners.
 

[J. Cook]

I'd have to pick either a 3-blade VPA, or the old 1 1/2" Magnus two blades.  For whatever reason, those are the 2 out of the dozens of brands / styles I shoot that I can get the absolute sharpest with the least amount of effort.  For that reason alone - I'd pick one of those 2. 

Woodsman's would be a close 3rd for me for the same reason - I've somehow just developed the right touch with my files on those 3 above all the other heads I've owned and used. 

[Wudstix]

I cheat with the Snuffer or any other three blade.  The 344 Stay Sharp system is amazing at putting scary sharp edges on broadheads with minimal effort.  Big Magnus 2 blade 160 grain is also one of my favorites.  I'll figure out the single bevel trick for these Wapiti heads.
 

[Tim Reese]

That’s way to much pressure for my OCD!!!

[Bob Morrison]

I've used many different heads over the years, if you put them where they should be all work as they should. With that the past several years I prefer wide 2 bladed heavy heads 300 Plus grains. The Old Magnus, the wide ones with insert to get to 300 gr. never fail to penetrate, even at the lower poundage I shoot now. I don't care for vented blades. this is my preferences, just keep them sharp.

[Dave Pagel]

VPA 3-blade for sure.  160 grain on woodies, 175 gain screw in on my aluminums and 200 grain screw in on carbons.

DP is

[Wudstix]

Like wide 2 blade: Magnus Mag, Centaur, Abowyer or 3 blade; Snuffer, VPA, Grizzly instinct.  All scary sharp and flying true.

I still have about 100 original Magnus BH that should last me until I am around 120 years old. By that time I expect that they will be reintroducing the old Butterfield Brute and then I will switch to that.

[SS Snuffer]

1  1/8   3 blade VPA's (344 sharpener is great) for blood trails second best Deltas for penetration and ease of sharpening. Been doing this for 60 seasons.

[PrimitivePete]

Magnus Stinger 150 grain, 2 blades, does everything broadheads costing twice as much do.

[JD Page]

Magnus Stinger 150 two blade. I have used them with great success and they are one on the best American made / warranty backed heads I can find. I will get a set of the Magnus single bevel once available as I like the bone breaking strength of that design. I am certain that there are other great ones out there but these are the ones I use.

[Kelly]

First off, must be a glue on broadhead so I can mount it my way.

Then it must be easily sharpened by me and re-sharpened in the field.

[Roger Norris]

Ace two blade.  Oh wait, that's the only one I use now. 

Beat me to it. Why? Easy to sharpen with just a file, and MASSIVE blood trails.
