let me start by saying that i have size 14 caveman feet, am 6 feet tall, and weigh 170lbs. Every playboat i paddled, my knees wouldnd fit cause of my big feet. I bought a used M/L four twinkie and my feet fit fine... but, i can only paddle for about 30 to 45 minutes before everything below the waist falls asleep. very strong hull. the chines make it fast for the shape and size. does good in holes and waves. rolls easy. the outfitting (first promo outfitting) sucks... thats the only word for it. absolutely horrible. the boat is light though. i put me a jackson footbag in the sucker and it does good. ive about folded it and its still strong. bashed the entire bow in and the next day it popped out and is back to normal. play wise... hard to get the bow underwater. ideal for river running. not for playing. this boat is definitely made for a heavier paddler. cartwheels probably are out of the question if your used to a boat with less volume and about the same length. pretty stable boat. not too edgy probably cause of the chines again... keeps the boat straighter easier. overall i would give the boat a 6 or 7. just bought a classic jackson fun. look for my review on that when i paddle it. seacrest out.
