Ok, I have the sb's in a 180 and they are amazing.  They compare to the ARV but a little stiffer.  The MSP is the stiffest ski there so if you have raced in the past and like stiff that is a good choice.  And the SCRATCH BC are okay but if you are gunna get a bc get the WRS, they may be fat but they butter nicely and are super sick in the park, fat skis are where it is at now.  I saw some kid with bacons in the park.  But anyways I like to ski a LOT of park and allmountain every now and then and my libertys are excellent.  And they have a 3 year warranty.  Cant beat that, and they have great customer service.
