Thanks for going the extra mile, man. I bought this board for my son after seeing the link. From what I have read, this GNU is touted as a park board but is actually a really good freeride - exactly what I was after.
Case closed bro - good Karma gotta be comin your way!
I'll be selling a 2012 151 rome reverb rocker here really soon. I got it brand new and only have 6 days on it. I am the same age as your son but this board just isn't for me. I'm not into park like the typical person at this age so this board is just way too soft for me. I bought it because I thought I wanted to get into park more but realized I don't.
