I am a beginning kayaker and have been studying videos of cartwheels for some time, but i have had only one chance to practice in flatwater so far. i still cant initiate my bow completely but i'm working on it (there are not many places to practice around here). While i was watching some videos i saw that kayakers tend to have to "double-pump" less when in a hole and i was wondering is it easier to cartwheel in holes or in flatwater? If i learn to cartwheel in flatwater will it screw me up when i actually get in a hole- when it counts? Thanks.
