It's fun to have something new, but to say that the new stuff is objectively better is a stretch, and if it is better it is astronomically expensive for tiny degrees of better. I'd be shocked if you gained 8 yards, but even if you did, would that change your game? It sure would lighten the wallet.
Again, I love my f7+. But I would not sit here and tell you it's better than your current driver. Looks great, sounds great, hits far. Better? Who knows. If you can live with buying a new club for fun mostly, and the prospect of it, MAYBE, being insignificantly better than what you have, knock yourself out. It's golf, not meth. You could spend money on worse things.
