How do you mount your 2 blade broadheads?
Many years ago when I went Trad, I was advised to mount 2 blade broadheads horizontaly. The logic was that if you tune your arrows well, you should be able to get rid of any porpoising but you will always have some archer parodox, so by mounting them horizontaly the broadhead would be less apt to cause the arrow to plane in one direction or another as it leaves the bow and before it begins to rotate.
The other day I was watching Byron Furgason doing his shot of the week. He set 2 playing cards on edge about a half inch apart and shot them both in half with one arrow.
I couldn't help but notice that he had his broadhead mounted verticaly or nearly verticaly.
I've mounted them both ways and most in-between and haven't noticed a rats-behind of difference one way or the other. If there's a way that's more comfortable for you then go with it.
Which ever way they are when they spin true! Pat
I agree with Pat. I couldn't care less how they're mounted as long as they spin true.

Considering the number of times the arrow spins before hitting the target, I am going to go out on a limb and say you cannot affect paradox or porpoise one way or the other by how you mount the broadhead.
I try to get mine to sit horizontally for one reason...it takes the head out of my peripheral vision. Other than that I can't think of any reason to go one way or the other.
I'm with Pat. I heat and spin until they are not wobbling.
I am thinking that, hypothetically now... for a short time, maybe two to three feet from the time the arrow leaves the string, it is not spinning. At that time, it COULD also be going thru paradox, that is, waving back and forth. If you have seen a high speed video of arrows in action, you know what I mean. If it is vertical, it COULD catch more air and move the head one way or another. If it is horizontal it PROBABLY WON'T catch more air, although the videos also show some up and down motion too.
Once it starts spinning, all of that stops mattering. I think.
Does it matter in the real world. I don't know. Probably not since a lot of you mount them verically and geet good flight. I mount mine horizontally ...and get good flight.
Something to talk about.

Ain't an arrow out there that comes off a trad bow only oscillating in one direction.
Bad MOJO for me Horizonal. But the kinda luck I'm having this year, I'm thinking of going to a 3-blade and try to get over the stupid superstition.
I have always mounted mine horizontal. That is just the way I like them. And yes, mounted/spinning true.
Read a story one time about a shot Howard Hill did, I think for a movie. It required an arrow shot and severing a vertical rope. Hill consistently hit the rope(no suprise), but the broadheads would veer off the rope and not achieve a complete cut. Story went on to tell of him making a broadhead with the blade in backwards so the open "V" faced the target/rope. Then it was a matter of shooting to determine the correct distance that the spinning arrow would reach the rope with the broadhead in the horizontal position and sever the rope. Maybe some of the Hill fans can verify this. Now I'm not sure how this would apply to your planing/paradox situation, but, I wonder if Ferguson's alignment of broadhead was in relation to the shot? His broadhead needed to be in an exact position when it reached the target. If the distance was somehow fixed, then his only options would be position of mounted broadhead, or maybe the amount of helical in the fletch. Then, again, vertical just may be his preference.

just to be odd....I do mine at a 45. Seems to lay over out of my pheripheral when I shoot. I like it, and it doesnt distract me one bit.
I do try and get them all the same , and if you take the time, you can get them to spin true on a woody as good as any carbon or alum!
Boy, I hope this doesnt get pulled for saying it. but 17 years ago, how I learned to do this was back when i shot compounds. Yes I said it, I started with a compound. Oh it lasted one year, then I bought a recurve at age 15. I've shot the same heads the hole time. Shooting with sites is where I really saw it. When I made the switch from the holy bad bad bad mojo peoples grounds, to the gooder then though boots, I rolled over this 45 degree deal and here I am today. Just a happy scared for life bowhunter with his bh's goofed up.
Steve,
That is right about hill doing the cut the rope hood shot.
I set all mine at 2:00.
I'm left handed and that means when I get to about 2/3 draw the blade is always vertical in my vision with a 10:00 cant to the left.
How it flys really has nothing to do with it,,,as far as I can tell.
