+1 - progressing with Starters is hard.
Looking at the OP, first priority are the wedges (+1 Courteney). Two short ones of those lvl40ish Pings will do for the moment.
Second, all the long clubs are of low level, i.e. low length and trajectory. Some intermediate help may come from a lvl47 Rapture 3WD (!), an unexpensive and powerful surrogate of a driver.
Third, it may be time to think of some custom balls to improve the approaches with some more backspin. Start with WGT balls, B-ES are nice, Tour SD are nicer. You'd have to allow for some credits vanishing on a regular basis.
Then, wait for the Master tier and for the good clubs coming - I second the G20 @88,515 XPs.
