Aaron and I took K1s out to try earlier this morning and wow! they really are very tipsy. Had some difficulty trying to get in initially, but managed to overcome that and was soon paddling around.
I personally feel that it is easier to turn a K1 than it is to turn a tourer. Unfortunately, I spend so much effort trying to stay the right side up that I cant focus on my stroke. Mostly using my arm power. All the bracing also put some strain on my shoulder and now its aching again. Ok. Will rest my shoulder from now onwards!
