Replying to Line bases and construction

Alright so i think ive probably decided to go with some chronic chryptonites (2011) for my purposes of all mtn charging and hauling ass + trees + pow when it happens + park/rails (still very important)

i have to be honest though, i'm wondering if this ski will be as high quality as the ar7s i was thinking about getting. ive heard things about slow line bases, will this be the case on the chronic chryptonite? this is a big question for me, if the bases/construction are very legit i'll walk out to buy these right now

PS, if i get them, how is the recommended mounting spot? would it be wise to bump them up a couple inches for park/rails or is there plenty of tail on them already?

thanks for any help, appreciate it
