Just hope there's not a huge adjustment period to it. My ex-brother-in-law who's got about 6 seasons in said that his riding level went back a whole year in his estimation when he bought a new board last year until he got used to it. I'm confident that won't be the case here, but we'll see I guess.
It's shouldn't be that bad at all...a year back is pretty sad, especially for someone with 6 season's in. Take note with your current setup on your binding placements so you can transfer them over easy and it won't feel foreign to you when you ride the first time. I wouldn't mess around with adjusting that until you are comfortable with the new board.
