About myself I'm 16, live in Belgium and I kayak since I was 14. I bought my Twintip 2 months ago. About the test environment I tested it on flatwater and it cartweels like ... You can still use it on class 3 to 4 with 2.5 meters jumps. Review If you want to learn how to cartwheel this is the boat you are looking for. It has great balance in waves and holes and it carves and spins without a problem ..... Conclusion The best boat I ever had (i only had 3), only the backband isn't as good as it could be but that can be replaced...
