Depends if you'e talking regular vanes fletched helical or feather fletched helical. IME, the feathers do as good a job with less weight on the back of the arrow and a lot cheaper.
Id be talking feathers. I still like feathers better than vanes. As of now I use simply a 4 degree offset with 4 inch feathers. Ive had no problems, but wanted to see what more spin would do for me. Im considering going helical or quick spin. Just needed more oppinions before I start building more arrows.
