Your options at lvl 45 won't get you to higher lvl's, say 80's without buying another driver if you buy what's available to you now. My suggestion would be to be patient and play as much as you can to get to lvl 48 and buy the Taylormade white with Aldila shaft that can get you all the up to the back tees and beyond. Your stats show you could use some help hitting more greens and getting closer to the hole, and also you'll be needing a better putter to improve your putting stats.
All the reviews for that driver say it will get you to the 80 lvl's, so you'll be able to save credits for better irons and a putter if you don't waste the credits you have now on a driver that will need to be upgraded before you reach those higher lvl's.
