I sympathise with your plight. With the benefit of top-notch broadband and a very good laptop (which gave me a super-smooth swing meter) plus the advantage of years of real and Tiger Wood golf experience) I hit Master at about Lvl 37 (I think). Given all of threads on here complaining about the swing meter and how hard it is to ding, I'd say that having a very good broadband/laptop combo was my biggest advantage in hitting Master tier early
Previously the game had been easy, now I was competing (or not) against all those lvl 60's, 70's, 80's and even 90's master's who could out-drive me by 50-60 yards and who had clubs with higher precision, forgiveness, flight and spin. I soon concluded that I could not compete on anything like a level playing field.
So what I did was target some of the esoteric awards (Hit the Flagstick, Water Boy, Choke Relief, Day at the Beach, Long Distance Putter, The Yips etc), for a bit of fun and bided my time until I had levelled up enough (59) to get some competitive clubs and then started playing tournies again. I also played with starter balls only for a while.
At lvl 73, you should be okay on the club front and if your computer can give you a smooth swing meter, then with a little practice you'll soon be okay.
