I'll try to add a little advice for what it's worth.....
A newer player should carry the best wedges they can afford and practice with them until they know exactly what to expect. Between full, punch, pitch, flop and chip shots, a 2 wedge set-up can be equivalent 10 extra clubs in the bag. 3 wedges offer even more flexibility but you'll have to give up your hybrid to get the third wedge in the bag. Good wedge players can sink or come very close to sinking (within 2 feet) their shots every time.
For those times when you just miss the green, good wedge play can help you get some birds and pars!
