Not sure how you feel about spending any real money, but if I was just starting out I would buy a few of the bundles from Stream platform. You can get:
___________________________________________________________________________
Fairway Bundle ($19.99):
Titleist T100 Iron Set (L0+) - 3,775 credit value, pretty good distance range of 110yd PW to 205yd 3i and decent meter speed @ 3.8 which will allow you to play cheaper balls for longer (since meter speed it the most expensive ball attribute).
6x Titleist Pro V1x Ultra Slow Meter Vapor Balls (L0+) - 1,275 credits/sleeve = 2550 credit value. (Only downside is if you get hooked on the super slow 6 meter speed you will end up paying 1,275/sleeve from then on). ;-)
5x Platinum Apparel Packs
100,000 Coins
2,000 WGT Credits - $20 worth of real money that can be used on balls, etc... and covers the cost of the entire bundle.
___________________________________________________________________________
Birdie Bundle ($4.99):
TaylorMade Milled Grind 60° Wedge (L39+) - 695 credit value (slightly faster meter speed than the above mentioned iron set, but still not bad at 3, and vastly superior to the starter wedges
TaylorMade Milled Grind 52° Wedge (L38+)- 695 credit value (same attributes as 60* above). The downside to this is you probably won't use it much with a 110yd PW if you buy the above mentioned iron set.
20,000 Coins
750 WGT Credits - I would personally use this to buy the TaylorMade Milled Grind 64° Wedge (L39+) @ another 695 credits.
___________________________________________________________________________
I would also look at the TaylorMade Milled Grind 56° Wedge (L38+) @ 695 credits. this would give you a decent gapping of 110yd PW, 93yd SW, 77yd LW(1), and 50yd LW(2).
So for $24.98 out of pocket (real money) you will get a decent set of irons/wedges that can probably last you up through the Master or possibly Tour Master tiers, along with six super expensive ultra slow meter balls, 120,000 coins, 5 Platinum Apparel packs, and still have 1,360 credits left over (2,750 - 1390 for the 2 extra wedges =1,360). Added to the 4,200 you already have that is 5,560 to go towards a better driver, and the Titleist one you mentioned would match your iron meter speed, which is not a bad thing.
Personally after I got a decent driver I never used a 3wd much up until Legend tier because the one I have is only +/- 25yds longer than my 3i with some top spin. And I only found myself really needing it on a few particular shots on a few particular courses, so I usually dropped it and carried a 4th wedge, but that's just me.
The only downside to this is I don't believe you can sell back any of the clubs you get from theses bundles since you already got such a deep discount, so you are kind of stuck with them for life (you can still upgrade stuff later down the line but won't be able to recoup any of the "resale value" of these).
