I have used the Flex Fletch SK300 Vanes these are a 3" vane, the Flex Fletch 360 Vanes these are almost 4" and I have been shooting the AAE Stealth Hunter Vanes these are almost 3" for the past two years with no issues. I have used the Stealth Hunter Vanes on several different arrows, with several different Broadheads and out of serveral different bows and they have worked great for me.
If you want to try some let me know and I will send you a few to try, I just received 100 Stealth Hunter Vanes the other day.
