anyone have any experience/thoughts about Kastle's sizing app on their website? I'm looking at the MX78 skis and it keeps putting me on 178's. But I'm only 5'7" tall, 175 lbs, fairly muscular/stocky. I'm calling myself expert (though I'm probably really a level 7+/ 8 skier), But I keep thinking I should be on the 168 length, esp. since I'm looking for the 78's as a carver.
Any ideas/thoughts about whether I should go longer or shorter? Or on the intelligence of the Kastle product finder app?
