I am the world's worst for saying go for it so bear that in mind.
Your tools are adequate, and L59 sees the first high trajectory iron set being the Ping G20s, are more than on the horizon. These should be thought of a must IMO - superb buy as will see you in to Legend and the L79 Bladez.
If you were in a CC I would say play some Par 3 tourneys for 400XP a pop to really eat it up, in conjunction with daily XP (one hole does that via Golf Courses in the Community Link).
B of Par 3 / 5 will also NOT affect your average score. There is nothing in the rules saying don't just play those a while. Sandbagging is only an issue when scumbags artificially manipulate to win credits, not some dude happily getting used to his tier for a little time really before for the next one. Tiering up before the correct equipment is available can lead to angst for the player to. Word of warning - don't go beating higher tiers (or is it just Legends - not sure on that 1) in MP as that will shoot you through the ranks at an alarming rate:)
I agree on the ball as referred to above.
Good luck on your path however you choose to play it.
