I got the Pings for 60, 75 and 90 yards and love em. I can stop house balls on a dime with them. Also I have not seen a bad review on any of the ping wedges but see negative reviews on the Taylor Made wedges all the time. Also when you get to higher levels you will need to upgrade your other clubs and I noticed the L60+ Ping G10 Set includes the 85 and 105 yard wedges so you may want to hold off on the longer wedges for later if you decide to upgrade the full set. 2 more levels and I will be doing just that myself.
The link below is an old chart but helpful for determining club ranges.
