What are you skating?
I'm 5'10" and tend to skate 8.25"-8.3x" and usually with a 14.375 or 14.5" WB. Anything bigger and it's a different world depending on what you do on the board. Something of a 15"+ WB screams transition, big transition. I'd say try their 8.5 with the 14.375" WB (that's my next board).
As for the construction, it's amazing. Super stiff and really poppy, after you get used to it everything else feels weird (tho P2s still feel as crispy).
The flights really do hold up very well but will razor tail just as fast as anything out there so if you have a shitty manual game, don't think it's gonna last.
Trucks...Go for ACE, you'll love'em and they don't SHRINK a WB, Thunders, seem to be the only ones out there that push the wheels out based on their geometry but even then it isn't much to worry about.
