Default Fletching: Offset vs. Helical

The last year I have only had a straight fletch and I am wanting to do an offset / helical to improve accuracy. What are the advantages / dis-advantages of fletching an arrow with an offset vs. a helical. I am a right handed shooter and use a NAP drop away arrow rest, so I would fletch a right handed offset or helical...correct? What is the best over-all degree to fletch either style? Any info would be greatly appreciated.

Helical fletching willgive your arrows more spin, thus more accurate groups. An offset fletch is better than a straight fletch, but a helical is better than an offset. The greater the helical the better, but you must be careful not to allow the fletching to hit the rest.

Isn't it true though that a helical will decrease the velocity of the arrow by a significant amount?

Slightly due to wind drag which is why it's better for arrow stability, is it significant or relevant....no and the advantages certainly out way the disadvantages.

And to your other question in your first post/thread starter, I'm a right handed shooter and us a left offset. Right/Left shouldn't matter unless you use matching offset/helical bladed broadheads. The direction of spin is not relevant.

So it would be better to go with a helical instead of a off-set...correct? Is there a certain degree of helical that is "just about right"?? What is a good fletching jig that can accomplish this task as well?

As stated above, helical will provide the most drag to the back of the arrow and will stabilize a broadhead better than just about anything else out there. That extra drag does not come without some compromose and that is long distance velocity. Out to abouit 35 yards or so, you will not be able to really tell the difference between offset and helical. Beyond 35, the helical will drop faster.

For the amount of helical, generally the clamp on your jig sets the amount and is not adjustable. For my helical fletches I also put on as much offset as I can and still keep the base of the fletch (feather or vane) in full contact with the arrow shaft. Let that be your guide as to when you have too much offset.

With respect to the jig, there are many good ones out there, but my personal favorite is a Bitzenberger. Somewhat pricey when compared to other jigs, but it is a joy to use.

The direction of right/left helical is important to people who still shoot off their knuckles. Not many of them around though. One way will cut your finger/hand, the other way won't.

I prefer a helical with feathers, offset with vanes.

NAP drop away arrow rest,

With a drop away fletching contact with your rest is no longer an issue the more helical the better. The spin that is created will improve accuracy with field points and be a very big help with broad heads. It"ôs just like the spin of a football the more spin the better. Be careful of your vane size 4" in most cases will do just fine. 5" will give greater twist but they are more apt to contact your riser. After you fletch your arrow spray them with aerosol foot powder. You will see at what point the rest looses contact with your arrow and if you"ôre fletching are hitting your strings or riser

I started using T-4 turbonocks with blazers and 4 degree right offset.
