You'll want to nail the balls to the pin when advancing, so precision and spin are important. That said, the "gold" is crap, the lower Ping is not an enduring investment. The level 41 Ping has been recommended here many times (BTW: @30,000 XPs). The 60 + 80 yds clubs are certainly a good buy.
A higher investment but with some advantage is the lvl 38 ATVs. They provide 50 + 77 yds, thus a shorter lower end. I like this, and I'm not going to give my 50 yds wedge out of my hands.
All these custom wedges provide you with a multiple advantage, since all shot variations improve compared to the Starters. A 50 yds full shot is accompanied by a 41 yds punch, a 15 yds flop and pitch (13 yds) and chip (6 yds) which can be executed with some perfection.
Be warned though that - provided a minimum commitment - you will advance to Master inevitably, producing the need for better driver, woods and irons.
