That is all personal preference. Many people are using Blazer vanes now. I am currently using Fusion vanes by Norway Ind. Super easy to fletch, accurate, plus they look cool
I have only used the vanes that have come on my arrows for now, however, my last 2 sets have been blazer vanes and i really like those a lot. They are very durable.
I'm using the Neon Fusion vanes. If you go here you can get a sample. http://www.norwayindustries.com/visitors/ I just got mine in the mail, although I already bought a package of them. The neon ones are great, they are REALLY bright.
Read this review of all the different vanes. It does not have a few of the newest ones (i.e. 3" fusions) but it gives you a good comparison.
Flu flu all the way! ...but seriously, most any kind of 2" blazer. I'll be trying the Neon Fushion vanes soon though.
I've been using blazers and i love them. Really durable and accurate. Going to try out these neon fusions as soon as I get my free sample in the mail.
