Two questions in one really:

What are the noted differences in performance between a zwickey eskimo and a woodsman (or magnus snuffer)? This is for wood arrows, so glue ons.

Also, should it affect your arrow flight at all to change from one (eskimo) to the other (woodsman) if they are both 125 grains?

Thanks!

Al three are good heads.  You won't notice a difference in arrow flight.  Depending on what I'm hunting, I shoot Zwickey Eskimos, Deltas or Woodsmans, and a few others.

Well tuned setup should fly same but check.

2 blade should penetrate better and the 3 blade cuts a larger diameter hole.

Example, I normally use the vpa 3 blade on whitetail and keep a 2 blade in quiver for large hogs. Same weights and both fly to same point of impact at 30 yds.

I have an assortment of broadheads in my quiver with my carbons with wood I might take a closer look but anything within 50 grain difference shouldn't matter unless you're borderline spine

Also penetration depends on the two blade I've had three blades out penetrates some two blades on 3 different Target mediums so just because it's a 2 blade does not automatically mean that it will penetrate better it depends on the head

What Terry said...regardless I would test your BHs and confirm before hunting

They can both work or both fail depending on the scenario; however, 95% of it is getting your arrow in the right spot. Just worry about getting something that is sharp and flies straight.

"borderline spine" maybe the most important observation in this case you asked about.  If you are tuned well and your spine is neutral/center, same weight BH should fly the same.
Penetration is always dependent on a variety of factors

I have shot the Zwickey Eskimo for many years without any problem with penetration.  The only thing you have to be sure of is getting them mounted properly.  Spin test them to be sure they are truly aligned.  I also have shot 3 blade heads, but find they are harder to sharpen.  You can't get the long bevel on them like you can on a 2 blade head.  Maybe I am just an "old timer" but like the 2 blade, especially the Zwicky head.

I get my 3 blades to shave hair or they don't go in my quuver.....alsi...if u get a 3 blade to shave hair you have a VERY durable edge that won't roll easy.

Do you use a similar sharpening method as shown in 3rivers' video on sharpening 3-blades? It actually seems like it might be a little easier than a 2-blade because the blades themselves also serve as angle guides.

I agree...:I think if you keep relatively the same arrow set up and broadheads weight then your arrow flight should be just fine. Just out of curiosity what are you planning to shoot with them?

3 blades to me are no harder to sharpen then 2 blds., like Terry my Snuffers or Woodsman will shave easily.

I can get both to shave, but I have to agree you need to consider the animal. I recently shot a hog with a very thick shield. The point of the broadheads was barely poking out the other side. The follow up shot barely penetrated, and I was using a razor sharp grizzly 3 blade out of a #65 longbow. Hove no doubt it would have easily gone thru a deer or anything else in North America. That hog had a shield that was as hard as I have ever felt.
