Wiredsport, great thread and some great advice, so here's my story:
I'm 5'9", 160 lbs and wearing a US size 9 Burton Hail.
Currently riding a 2009 Jam 157 for piste charging (at which it excels) a couple of weeks a year when work allows and a few trips to the 100 Yds indoor snow slope just to get my fix in between.
I need to add to it something slower with more flex for two reasons, firstly the Jam is a bit of a beast for 100 Yds of slope, by the time I get it half way to its potential I'm queueing for the lift, secondly on piste I need to escort my beginner wife now and then so I want something more playful to keep me amused while she perfects her turns and picks her butt off the floor, holding the Jam back is a calf muscle killer. I've got little experience at butters, presses or even ollies and don't think the Jam ideal for improving these.
I was looking at K2 WWW and tried out the wifes K2 Luna for laughs when I realised how much I loved TBT, I do enjoy spinning like a loon without catching an edge. I saw the 2012 catalogue online and after reading up on all the awesome looking new TBT found I was leaning towards the new airobic.
So the Jam stays, no question and I want something to add to it, don't need one board that does a bit of everything, just one a bit playful that can handle basic tricks without kicking my butt, maybe the odd rail and kicker too. So jib versus twin, airobic versus ET, disaster too soft for my weight? Your thoughts on board and size would be appreciated.
