At lvl 70, quite a few good clubs are available.
The 3rd wedge is a good proposal, alas only necessary if there is a gap between PW and the others, taking the punch shots into account.
The Pro driver has 245 yds. A budget replacement for this might be a strong 3WD (230-240 yds), 1/3 of the cost and of multiple use on tee and fairway.
The G20 (lvl 58) has high trajectory, the RBZ (69) is med and a wee bit longer, yet more expensive. The Rapture (47) is shorter & med/high at a budget price.
Of course this may not be the final set-up for a Master but not wasted at all.
Also consider to use some cheapo custom balls - also a big improvement for 1 cr per 9 hole game!
