I am trying to figure out some good vanes for my new arrows I am building. I will be using 4 fletch and arrow weight will be 520-550 grains with a 125 or 150 grain broadhead. Haven't decided which yet. Should you look for more surface area, more height, more length? How much is enough, I want them to be accurate but I also don't want uneccesary weight at the back of my arrow. I am looking at trying the Vanetec V-Max series in 3 inch, the Vanetec Swift cut in either 2.25 inch or 2.88 inch ones? Most likely I will be using a straight clamp with a good amount of offset.
