RE: Arrow wobble
 

Am new to site but thought I would add my recent experience.
I found the same thing with my bow after adding a new sight.
The cock vane (at 12 o'clock) was wrinkled, wavy, curly however you want to say it.
The pro shop sniffed it out immediately.
First problem: Nock was not set properly. Was too high which threw the arrow out incorrectly.
Second problem: My sight was mounted too low and the cock vane was rubbing the bottom of the sight every time.

They reset the nock and moved the sight up and problem solved!

They told me to spray the vanes with foot powder spray to see if there was any other places of contact.

Incidentally, I shoot with a fall away rest.
