My son has been snowboarding for one year. He's 13, 5'3", size 8 shoe, and 95 pounds. I know he would like a Burton board and I am considering the Custom Smalls 135 (or possibly the 140). Is this board too advanced for him? Should I go with the smaller board for more control even though it has a 234mm waist? The 140 has a 242mm waist. Thanks for any help!
