thanks guys... all that pretty much is logical... so is there any advantage that the 3rd blade provides that makes up for the loss of diameter??? and any scouting reports on the 3-blade bloodrunners???
A good comparison is total inches of cut.
Cut = broadhead diameter divided by 2 times number of blades
a 4 blade with a 1" diameter gives you 2" of cut
a 3 blade with a 1" diameter gives you 1 1/2" of cut
a 2 blade with a 1" diameter gives you 1" of cut
a 4 blade, with a 1" diameter gives you the same cut as a 2 blade with a 2" diameter
Make sense?
More important than broadhead diameter and number of blades is shot placement.
Put it in the vitals and they'll all kill. There ain't no different degrees of dead!
A two blade will generally get you better penetration but a three or four blade will cut more tissue which can give you a better blood trail. A three blade is a good compromise.
You do NOT have to align anything with anything. Fixed or mechanical it does not matter.
As long as your rest is centered properly, your field points and broadheads should fly the same. I still shoot 3 blade Muzzy's and I don't have any problems.
there is zero need to "align" a broadhead and basically the big difference between 2-3-4 blades is what every tickles your rear.
A properly tuned bow will shoot most any broadhead where your field point is. A properly placed field point will kill a moose.
Turning a broadhead so that it's a certain direction is almost funny considering your fletching is beginning to rotate the arrow almost at the point of release. So having it parallel, perpendicular or any other way simply doesn't matter.
tune your bow, it takes an hour-ish and will make all questions about "what BH groups the best" irrelevant.
Actually the orientation of a broadhead does make a difference that will show at yardage. As a release shooter the most prolific oscillation of your arrow will be up and down ( side to side for a finger shooter ). A two blade broad head launched in the horizontal plane will track in the position of first oscillation. One should make every effort to align two blade head vertical, like an I
Four blade heads can also have this problem if launched in a + pattern. Indexing a four blade head in a X pattern keeps the blades from having a full profile in the oscillation plains.
Three blade heads do not have the problem of a two or four blade as only one blade can be in the horizontal or vertical plane at launch. Aligning a good three blade head with fletching is not as important as having your stiff spine side up or down with all the arrows used with a three blade making sure you have enough fletching for the three blade head.
Mechanical heads are not as subject to the alignment as they are not a full profile head and the plane effect during oscillation is reduced. All heads can benefit from these practices. Physics is physics.

this is about what I was looking for... the only thing I don't understand is why release shooters' oscillations are up and down??
