The 169cm Kung Fujas I ordered measure in at 170cm from tip to tail. Oddly, the 172cm Line Sir Francis Bacon measures 168.2cm tip to tail (though 172cm if you run the tape measure along the bottom of the ski, which takes into the account the rocker curve). Go figure... manufacturers really need to stop getting creative with these measurements.
Same with ski dimensions... last year I almost ordered the Rossi S3 thinking they were 98mm underfoot, but after some research realized that they were only 93mm in the 168cm length (also not really 168cm). I was upgrading from 83mm and wanted more like 100mm width, not 90mm. Maybe they're great, but weren't the increase in surface area I was looking for.
