Congratulations VH. For me the master tier was no more challenging then the rest of the tiers. Each tier brought a new challenging element to the game.
Upgrade your clubs and practice your long iron shots, you'll do just fine.
I like forgiving clubs, some like precision, my advice is, take advantage of the club rental feature and find out what clubs your comfortable with.
Your a good player VH, you'll do just fine. Play a few practice rounds and dial in the yardage on your new clubs, especially on the par 3's.
Good Luck friend. Practice well.
