Right Bevel vs. Left Bevel

[raisins]

this is the guy that i was looking for, he has several videos about this subject, i believe, but this is the one that first sold me on clocking my arrows and fletching in the same direction

anecdotally, i've noticed that my arrows appear to spin faster now

this guy has great videos

This is a great video. After allot of conversation with my bow tech. It seems the more spin the greater the parachute effect and slows the arrow. This is my logic behind right helical and right bevel along with availability. Seems to be enough to help steering but not enough to slow the arrow with parachute effect. Now this is only my opinion and thought process so don’t take it to the bank or quote me.

i think parachute effect comes in at much longer distances, i've never experienced it shooting out to 60 yards with a mid to light arrow (380 and 415 grain arrows) and hard helical out of an arizona ez fletch mini and minimax

I greatly appreciate all of the very informative replies, gentlemen!
I've always had left wing fletching, to some degree. Either left off-set or left helical. However, after watching these high speed videos of the rotation with matching left wing/bevel, I'll be matching everything up the same.

I finished watching a "front porch discussion" with Dr. Ed Ashby. He says that when a left wing fletch and a right bevel broadhead is used, the broadhead acts like a double bevel broadhead and doesn't have near the effect, as it was intended.

Thanks again, BowhunterXC

Im not very well versed in it. It’s just been my deductions and personal preference. I’d like to see a video with 4 fletch low profile. Allot of 3 but very few four. I’m on my first set of four fletch at 2* and I’m having great flight out of them.

Pretty in-depth about tuning but at about 18 minutes discusses 4 fletch with turbulator and A%A fletching.

Thanks I’ll look at

Ron Kulas (Innovative Outdoorsman/ Stay Sharp broadhead sharpener jigs) did a video where he demonstrates what Dr. Ashby claims. TLDR: In flight the arrow rotates ad per the fletching. The the bevel is opposite the fletching, it will reverse the rotation upon impact. This process of slowing and reversing the rotation has the effect of minimizing the rotation. IIRC, the energy this takes saps penetration as well. You'll still kill the deer, but you're leaving capability on the table. Might as well just shoot a double bevel at that point.

I just checked it out seems interesting I prefer a four fletch so far with a two blade fixed. Just like it
