I bought a set of Brush-Ts at a golf show last month and recently had the chance to try them. After just a few holes, I think that I agree that they are a superior design to the wooden tee. At the very least, they’re more durable. I normally break a tee on every hole. Obviously, these won’t break.
As for hitting it longer and straighter, I don’t know yet. I hit two balls on a couple of holes — one with the Brush-T and one with a wood tee. I did get a better flight with the Brush-T, but it was too limited a test to be sure. I’ll have to experiment some more.
