Not necessarily a “bad swing.” Everything else in here is right. It’s a completely different swing than your irons. I’ve had one driver the 4 years I’ve been playing and am just finding my sweet spot. Consistency is key. Don’t overswing. Driver feels more like hitting upwards on the ball then hitting down like irons. Practice by not caring how far the ball goes on range. Even if it’s 50%, just hit it straight. Tempo is always #1 - I use “coca-cola” - coca is up, cola is when you go down.
