I'm currently useing just a slight helical Left wing, but see some guys with a lot of twist/helical. How much is to much (any down sides) and what's just right?

Too much is noisy and will slow the arrow needlessly; another personal preference thing.

As Bjorn said, It's another personal preferance thing...

That beling said... There's "helical" fletch, usualy about 11 degrees. and then there is "offset" which is about 5 degrees.

Most guys are content with a slight offset fletch. Not me!!! I like as much helical as I can get!!!!!

as much as my skinny arrows can handle. I don't think you can ever have too much .

Whatever the bitzenberger jig gives me.  it is alot.  I shoot 5.5" parabolic feathers.  

Just like woodchuckersais as much as my Jo-Jan will put on with 5"+ feathers.

I want as much helical as my arrows will allow. I'll sacrifice a few fps for more stability and accuracy.

What Joe said accuracy mrans more to .me than speed

I'm in the all I can get crowd. Stability and a twisting broad head is were it's at. A top that spins fast stays straight and upright for a reason. Same theory! The loss in speed is moot in compare.

Been experimenting lately with a bit of a mistake.  I have about five dozen 5 1/2 inch feathers in several colors.  I waffle back and forth from three to four fletch.  I figured
it was senseless to just let those feathers sit and collect dust so I just clipped off the last inch and a half.  The feathers have this wicked profile--very pointed--and are big, though short.  I fletch them four per shaft and the amount of helical in them is wild.  With this configuration, CE 150's cut to 29" with a 134 gr. Magnus 2 blade out a Pronghorn one piece fly just as wicked as they look. They DO scream a bit more, but the flight is just cool.  I see no appreciable decline in speed. I re-fletch like a varminter reloads bullets and find the experimentation the most interesting part of the process.  I will shoot this set up for river bottom whitetails in December.  Have not "worked up a load" for the 'curves yet. The most helical my Bitz will twist!!!

AS MUCH AS YOU CAN GET WHILE STILL MAINTAINING SOLID QUIL CONTACT FOR GLUEING,  FROM END TO END ON YOUR FLETCH!!!!  If the quil of the fletch is rolling too much up on its edge to make for questionable surface area contact between quil and shaft,  they will not glue up nice....and wont stay on long.  You may have too much helical in this instance.

not too much for Aluminum ( straight ) Shafts More for wood.
