Next season will be my wife's sixth playing golf. She's on her second set of clubs. It was important to me that she began golfing with decent clubs. Easy to hit in the air, forgiving. That said, we went with one of the Adams full-set options. Comes with bag, putter, full set, pretty much everything.
This is where it gets interesting though: Her game for the first 3-4 years was limited to literally 4-5 clubs. Driver (TM Burner purchased later); a 5 hybrid (Cobra, purchased later) 7-iron, SW and putter. She used to play nearly an entire 18-hole round with those 5 clubs.
At the time, the full set of Adams women's clubs came with driver, 3w, 5w, NO HYBRIDS, 5-SW and a putter. Truly a 'full bag' of clubs for a beginner. No wonder it took her 3 years to figure out 'what club should I hit!'
Knowing what I know now, getting the right club complement as opposed to the full set is probably the better route for the beginner. Nothing wrong with buying used, either. Just make sure the clubs are within a couple years of being new.
Possible choices: Get a 460cc driver, one hybrid and maybe the 7-SW iron set. Let her swing a bunch a putters and find one that feels good to her. I didn't realize how important this was to my wife in terms of MAKING putts!
The reason the set makes sense for my wife is that she hits driver off the tee on any hole longer than 160 yards, which turns out to be MOST of them anywhere we go. She moves the ball down the fairway consistently with the 5-hybrid. Inside 100 is when the short irons come into play. Around the greens it's SW and putter. Honestly, when we took 5-6 clubs out of her bag, her game significantly improved.
Probably more ways to skin a cat here, but wanted to share my wife's experience. The best news is that she loves the game. Makes for fun Sunday's during summer and fall weekends getting to play together.
