Am I the only one that is not surprised that his first driver was a Groove?
As for a driver that is beginner friendly, anything that is speed 7-8 or 9 should be fairly forgiving and allow you to learn proper form. So things like a Trak, Teebird, Leopard, etc. would work. If you really want to get better quicker, you should play like no one else so later you can play like no one else and use just mids and putters until you can throw a mid 250-300' like LB397 mentioned.
