as far as brand-names go, i've been very happy with Titleist Vokey series wedges. i played Cleveland before those (which i also liked).
Vokeys, for example, are generally denoted by loft, grind/bounce as opposed to GW, AW, SW. currently, i'm carrying three:
52 - full swing = 95yds (i can get another 10 if i jump on it, and can 3/4 swing to 85yds pretty easy)
56 - full swing = 80yds (this becomes my all-purpose wedge from 80 and in, can open the face for shorter shots that need to stop, and play the ball back for bump-n-runs)
58 - full swing 60 yards (i use this club almost exclusively from the sand since it's got a pretty high bounce, which i tend to blade from the fairway.)
i'd go to the local golf shop and hit some in the cage to see what suits your desired full swing yardage, and what feels good in your hands. locally, Golf Mart offers a 90 day exchange policy on all new club purchases, so i can play with it for a few rounds and take it back for a different one if i need to. better yet, head to the course and see if the Pro-Shop has a demo that you can take out for a round (or on a range w/ real grass)...it can be hard to get a feel just hitting off mats.
