4 and 7 Wood vs 3 and 5 Wood

Almost everyone will hit a 4 wood as far as they can a 3 wood, some further, and easier too.
Those who haven't tried it should.
Having a 4 wood negates the need for a 5 wood so moving to a 7 wood, or equivalent, is sensible.
I've used 4/7 for years. Well, kind of....
My 3 wood is adjusted to 16°, so a 3 1/2 wood and the 5 is adjusted to 20°, a "6" wood
Still experimenting with the best settings but I won't be going to a 15° loft as it's no different in distance to 16° but is easier to hit.
Having 2 clubs that you can only use from the tee is a waste and some people can't hit a 3 wood from the deck. Swing "learn how to" implies that we should all be using blades down to a 1 iron.....can't hit it? Well learn how....I don't think....
