When I think about my iron/wedge set up, I want my gapping fairly even (10-15 yds) through my irons to the 50° GW at 100-110 yds. Beyond that, I'm looking for my SW and LW to complete their tasks in the sand and around the green, and I'm less concerned with their full "carry yardage". For the sand at my home course, a 56° with 10-14° bounce works well, while I prefer to have my LW at 60°/6° with a round grind to give me more creativity off varying lies.
Sure, I can hit my SW 90-95 and my LW 75-80 with a full swing, but do I need to? Most of the time, the answer is no. Swinging hard tends to increase spin too much, and can result in me spinning it back way too much, or the shot blowing up into the wind. It's much more common for me to take a little more club and flight the shot to get the right loft/spin for that particular approach.
Long story short, I would recommend you play with your clubs and even take several different shots (when you can) from varying distances from 100 yds and in. Find the wedges that will get you up and down from the sand and when short-sided to a tight pin first, then worry about their full carry yardage afterwards. Good luck!
