Nah... 2012 SL 155 is utter crap. Terrible edgehold, noodle-ly and washes out every turn... you should put it up on Ebay ($100 starting bid, no reserve, 1 day auction) and get rid of it.
i agree. and make sure you let us know when your putting it up.
In all seriousness though, I think everyone should account when testing out a new board the first day of the season after 2 riding the same board for 2 years that it WILL feel different. I am very comfortable in my riding but my first day out riding every season is defiantly a little shaky compared to a mid season ride.
