If you can climb 13a you have to get on this one. You really don't need to be 13a strong to pull the moves and even clipping the chains is only 12d or so, like EM said below, it's that topout that gives it the 13a rating.
I personally feel that it's a bit softer than other 13a's I've done due to all the rests and the great quality of them all. Very fun though!
Top out is a must for full 13a grade. Clip chain and continue on, then down climb from the top (similar to Body Wax).
Definitely stick clip the first bolt. If you're short (I'm 5'3") you have to jump or do a harder start (head first) to the opening hold but taller folk can just reach. If you jump and miss it's a clean fall - I've done it once... Several good knee bars. Be mindful of climbing when wet as to not break off holds.
