Best 5.10c Squamish crack IMO! This is a must for any self respectable leader.
High on my list are also the 4 pitches of Bulletheads East, and Rainy Days Dream Away. Arrowroot and Rutabaga are not bad either!
So many good finger cracks in Squamish! 
Can't speak for the 2nd pitch as I have only climbed the 1st.. but I have climbed that a few times as the gear is so good. It is nice as it is only 10a on the first pitch and if things go sideways you can very easily clean aid up to the anchor to position yourself for a gear retrieval rappel... so relatively low commitment factor. I have watched a number of good climbers flail on the 2nd pitch so I am wary of it. :)
