I just thought I would post this: the Kastle MX78 is unchanged for 2013. They re-numbered the length to 178cm from 176cm. Same ski as last year, same length. It is still 2cm shorter than the MX88 in 178cm, and 2cm longer than the LX92 in 174cm. The graphic guy might have just made a typo and the 176's all became 178's when the topsheets were printed.
If you liked last year's MX78 in 176cm and were freaking out that they changed the ski for 2013, don't worry about it. The only change is the topsheet number.
