Can't comment on the BSOD, but I absolutely love my Flagship for pow and good morning groomers (mentioned this sooo many times in this forum, won't repeat all the chorus of praise [hint: use search function
], thus here only a short version):
on the + side: super stable at speed, very fast edge to edge, great float
on the - side: teeth-ruttling stiff, PITA in spring crud/moguls
Gonna borrow the words of an other member, which describe the board pretty nicely: rock solid confidence going fast in pow... On the other hand, FS had all the sprightly nimbleness of a garage door in tight trees and glades, it just basically wanted to go straight down.
