hi,
it’s a known problem with the sticky trim and on my 2011 it don’t help to push the bar away. The only possible thing is to have the kite above you and let go of the bar and fast pull the lines and pull the trim before the kite hits the water. (or just let the kite go in the water and trim it then. not good when lots of kites though)
Yesterday I found one item in my bag which I have missed when I god my bar. It was some kind of pulley that should solve the stick trim problem but to follow the instruction you must be a rocket scientist 
Otherwise the fusion bar is great. I have both the freestyle and fusion but use most the freestyle just because of the sticky trim. On better ting with fusion compared to freestyle can be that if you miss a hocked in trick the kite depower more with the fusion bar when you let go of the bar.
I really don’t know why they don’t fix this issue with the sticky trim.
