It's a crux of many wedge sets that they are missing a 50-60 yds club, or that their yardage is rather weird.
One workaround might be to use a short lower tier wedge, like the L40 ATV of 50 yds. I started with them (resp. the former Z Satins), and I kept the 64° (50 yds) while upgrading the longer ones. It blends in perfectly, and it performs well enough for me, concerning roll. With the longer Satins, roll was too much though.
Of course, a top player will need three top wedges, but for recreation, it might be enough. In fact, I have three different types, a reminscence to one of the best, Bollox.
