RE: New to archery... opinion?
I don't think so raxxmaster....They are super sharp, cut on contact and don't burn up NEARLY the KE that an over the top mechanical does. Since the blades open on contact, you are basically shooting a fixed blade head, without the worry of erradic arrow flight.
I will agree that the large cutting diameter creates some surface tension, but not any more than a 4 blade fixed would.....
