bin shooting 2 blade deltas this year. i got used like them so far.Was going to get a new set for the season.Was wandering would i be better off with the 4 blade? Does the bleeders make that much of a difference.

I am kinda interested in the same opinion on 2 blade vs 4 blade...

I like the two blade just for the ease of sharpening.

i believe i can get either hair shaving sharp 2 blade just a tad sharper.im more thinking twards the blood trails.does the 4 blade really makes that big of differanc.

What is your arrow weight, true draw length and draw weight at that length, and what are you planning on hunting. I am considering using the 4 blade Delta's this year also and these were some of the first things Terry Green asked me and he's been shooting them a LOOOONNNNGGG time.     Either head is a great head and the bleeders really aren't hard to sharpen if you watch how Terry does it in the how to section. The two blades are wide enough though if you don't have enough bow weight or arrow weight to shoot the 4 blades to leave a very nice blood trail though.

My setup is 48# at 28 my draw is about 28 1/2.Im shooting legacy 2020 cut to 31. head is delta with a long alum adapter.Believe total weight is around 594.bow is a predator classic.bareshafts are grouping together along with broadheads and field points.might move up point weight would like to shoot shaft around 29 but still tinkering
 I know terry kills lot og game does he only shoot the 4 blade?

sorry will be hunting whitetails and black bear

Terry usually shoots the 4 blade Delta, or 3 blade Woodsman. I think for deer you would be fine with the 4 blade. For bear I would still opt for the 4 blade but keep one or two 2 blades in the quiver in case a really big bear showed up.

James, with your setup you will do fine with either, IMO.  If you have penetration concerns in the back of your mind, then go with the 2 blade.  You must have confidence in your setup.  Arrow flight, sharpness and placement are the key with any broadhead.  The Zwickey Delta, 2 or 4, is an excellent choice.

Never shot the 4 blade, but be it 4 or 2 blade I think the end result will be the same......an easy to follow blood trail.  

I prefer single blade heads. I shoot Eskimo's and Deltas and both resulted in dead game. The 4 blade will take some time to sharpen(bleeders) but open up a larger hole.

Take your setup, shoot an arrow with each broadhead from 20 yds into a large sand pile. See which one penetrates the farthest. At least you will get some idea about your penetration.

I think with your setup either head would be ok. Now if you were going for elk I wouldn't even think of using the four blade with your setup. I just use two bladers on everything. I like them.  Gary

I vote 4 blade. But I have this thing for overkill... If I were hunting whitetails instead of elk, I'd shoot the four blade Simmons heads instead of my two blade Simmons tree sharks.
I think Terry almost always uses 4 blades, but I could be wrong.

I've been shooting the 4-blades for at least 50 years now and I think the bleeder blades do make a difference in terms of blood trail and pass throughs.   If you're shooting a lighter pundage bow you may not get as much penetration with 4-blades, but I hunt with bows in the 55-65 pound range and the 4 blades work great for me.

RkyMtnJoe hav u shot both and believe the 4 blade does make a diff.i was just trying to decide if there worth the extra time to get sharp over the 2 blade.I can get the 2 blade scary sharp in sec.it take me some time on the 4 blade.

Someone need to make a 4 blade stone that the slot is wider so you can sharpen the bleeders on it.Mite have to tinker with that idea.

The bleeder blades get in the way when I try to sharpen the  larger blades so I just ground the bleeders off.

Been shooting Zwickey deltas for nearly 50 years, mostly the 4-blades. They do make a bigger hole and leave better blood trails IMO.  After some file work to true up the main blade edges, I use tru-angle file and hone blocks to get them razor sharp. I use a file to sharpen the bleeders, then strop them on the hone.  Quite easy to do, actually.

Small world dink, I'm from Somerset originally.

I really prefer 4 blade for blood trails, unless it's a land shark then two is more than enough.

Just for what it's worth...

I've killed a bunch of hogs (way more hogs than deer but I've killed deer with everything from mechanical to muzzy's to Steelforce, Magnus, and Zwickey) with a bow. No matter what I am shooting I've always managed to get more penetration from 2 blade heads. That's carried over to deer too. I sent an eskimo thru a deer's shoulder last time. 180lb buck. Got the head back and it's fine. Hard to beat the 2 blade heads IMO.

All other variables being equal, the 4 blade head will only leave a better bloodtrail if it's  sharper  than the 2 blade.
