Thank you for your advices, I will evaluate them carefully and experiment.
Yesterday I took off the rubber which are around the handle, this to make it smoother and avoiod my bow hand to twist or jerk on the bow at release. The rubber BW put on makes your hand stick to the bow... too much acc to my liking. When i removed it I belive there was some improvement, but I am not sure because it was a windy day..., I will try some more this afternoon.
Be the way, when I say fish tailing I mean from side to side (like a fish).
It is actually very interesting what you say about tilting the bow too much compared with pulling hand. I have been thinking about the same thing, actually i switched from glove to tab for rectifying this problem... this helped but maybe not enough....
