Kiwikidz: any suggestions on affordable wedges and lofts would be great or would I be better served getting a better putter?
Wedges before putter, all the time! These Starter wedges are total crap, especially with the variety of shorter shots, while the putter holds itself quite good. A high level putter certainly is better, but you need to make your choice between "Ding putting" and "Off-Ding putting" first.
The suggestion of three wedges is valid, but it requires some thought and calls for a more durable choice of irons than your L10 ones. This is because the three wedges should fit below the PW in an (ideally) even spacing. High level irons have about 115 yds PWs where a 100 yd wedge is a good fit. (105 is also available). 50-75-100 or 60-80-100/105 are common choices.
For you and for today, two wedges may be sufficient. Make your choice from 50 or 60 yds up!
Have fun!
