With the test board, I mean the board that's available for rent at the local snowboard shops. Like this one:
If the link wouldn't work, it's the board with black text on a white cover. (As far as I know, this board is already known on this site. BTW, this board is normally not for sale.)
In Austria I tested the 157cm and the 163cm test board. For me, the 157cm felt a little to unstable at "higher" speeds on the slopes.
Seen my weight and length I'm looking for a 161cm (somewhere in the middle).
The (official) Evil Twin only comes until 157cm. That's mainly the reason why I'm hesitating to chose for the test board. I don't want something that's "not right" -if you know what I mean-.
Moreover, I'm unsure if the tech on the Bataleon boards has changed a lot over the past two years.
If necessary, I'll just wait until the ET or Goliath 2013 model comes into discount after the season.
FYI Riding style:
+/-10 days indoor (rails:no, jibs/boxes: yes)
and
Two weeks cruising along the mountain
So no jumping, halfpipe or any other crazy stuff. (I'm too old for that

)
Thanks for the feedback guys. I appreciate it!
