I would like to buy a Kessler X Carve, but I'm not sure about the length. Until now, I've been using a Jones 9000 for carving, but I want to push myself a bit further. Since I keep a board until it can't handle it anymore, I'm looking for something that allows me to grow technically. I am 180cm tall, weigh 66kg, and wear size 43 boots. I am very athletic and have been snowboarding for about 20 years. I'm torn between the X Carver 159 and the 164. I have always used, and want to continue using, soft boots. Regarding the slopes, I ride in a place where the snow is often very hard; perhaps a few extra centimeters of edge could be useful. Thank you, I look forward to your advice
