Wedges often decide whether a missed green becomes a bogey or a saved par. Still, many golfers buy wedges almost by chance: a sand wedge comes with the set, later a lob wedge is added, but loft gaps, bounce and grind receive little attention. That is where a lot of improvement is possible.
If you want to buy wedges, do not look only at brand or appearance. The key question is which shots you actually play: full wedge shots, half pitches, chips around the green, bunker shots or high lob shots. The clearer the job, the easier it is to choose the right wedge.
