Perhaps More important than fletching is The arrow tune & tune to your bow. Suspect I am getting ahead of your learning curve though this is important. Spine alignment & proper point weight for the spine of your arrow is vital. Preferably a heavier point weight as long as your arrow is of proper spine for the point weight (high FOC - High front of center).
With a properly spine arrow for a high FOC point & spine indexed you may be amazed at achievable arrow flight with bare shaft. (no fletching) Achieve this then I prefer small vanes for hunting.
Speed is of less concern to me these days. If RF don't turn you off too much he offers some good advice. While I like nearly all his advice. Grizzly stick happens to be my preferred Arrow & BH vendor.
