You're still a tad low in levels (43) for good drivers, and you need a GOOD driver when becoming a Master. Wait until then!
Instead, you might start with a 3WD replacing the Starter driver. They are a third of the drivers and help you twice, on the tee and in the fairway. The Max 3WD coming up to you @L46 is a real bargain!
Or, go with the full MAX club set @L47!
An even higher priority for me are the wedges. You're now good to buy two of the Taylormades @L39, 64° and 60°. These are game changers!
Concerning the characteristics, more points always means "better", so a higher number on meter speed means "lower meter speed" and speed slows down.
