Just the opposite. The portion of the board with no TBT is long while the TBT portion is narrower. The board is directional and stiffer. Those elements are designed in to promote quick edge to edge transitions, a stable platform underfoot, max lift to the potential ice catching contact points. As always, the correct design for your conditions and style will be the easiest to ride. The 158 will be an exceptional choice. You could bump up to the 161.
Aha. I see. Thanks.
Not really planning on buying a new board next season but I see that the Omni is only like $480 retail and it will be even cheaper towards the end of the season so might jump on one.
Also, noticed the 2012 158 Omni has a mellow sidecut of 8.45 and the 156 Jam has 8.05 and 159 Jam has 8.20.
Have you ridden the Omni or Jam Wiredsport? If so what was your experience with them.
