Fletching

Woodely:
To spiral or not to spiral.  Is spiraling the fletching that important, I could see it at close shots but anything over 10 yards and the paradox goes away correct.  I always install the fletching straight on all my arrows.  I have noticed the odd arrow that porpoises near the 25-30 yard mark.   They are fine at 20 yards  :P

Woodely, I have tried straight, and RH fletcht, 3", 4" and 5". out to 25 yds. I shoot a long bow, 43# and light wt, wood arrows, 370, to 390gr. I saw "almost" no difference in the flight of the arrow. I made 3 sets of each RH 3,4 and 5 and 3 sets each straight. The RH 5" fletch showed a very slight decrease in velocity thru my chronograph, ,on avg., 2 or 3 feet decrease at 20 yds.  I even took the fletching down to 1/4" high on the straight and RH 5", mixed the arrows, and saw little difference in the impact area. I did this over a 4 day period with a few hundred shots. I would say if your bare shafts do the same when setting up your bow/arrow combo., why wouldn't the results, bare and fletched, be close to the same. 

Pat B:
I've always straight fletched with a slight offset. Your arrow will spin even with straight fletch because of the texture of the feather.
 I think with the "slower" bows we shoot the stability imparted by the spin isn't as critical as it would be with a bow shooting 300fps.

rebsr52339:
Pat is right on the straight fletch. There is a slight offset in the fletching even when the core is straight and parallel on the shaft.

Woodely:
Sort of what I thought about the diff between spiral and straight,  some guys prefer sprial over straight because of the paradox and snaky flite after release.  I use 4" fletching because I prefer more clearance using the glove and a lower brace height.
