You might want to try the higher profile 2.1 fusions (not the x ii) with a fixed head for added steeringif going 3 fletch. They are .55 high while the x iis are .43, which is why u see a lot of guys add the fourth vane with the xiis. I have been shooting the regular 2.1 fusuons and will be trying the x iis this year but I shoot sevrs which are really low profile in flight. I actually have some extra of the regular fusions and can send you 9 to fletch up and try if you like to go along with the xiis if you order those. Pm me your address if interested
