After training for this trick a lot it was still a lucky trick. Sometimes i would have the feeling to do a few in a row... next session none at all.
I have had really variable success with the taz too. I found it silly easy on Rob's (I think) NFX at Rougham, and I love the way R-Sky kites look with this trick - so smooth and clean - but have had limited success before and since with my own kites.
However, yesterday I made a big breakthrough by simply executing the taz higher in the window. Reckon I increased my success from 10-20% to around 70-80% (and nice-looking ones too) with this one modification. Not quite sure why this should be? Less chance of a tip wrap perhaps, which allowed me to let the nose of the kite to flare away more before initiating the spin?? Jason's advice also helped - cheers
Or maybe it was just one of my lucky sessions, time will tell...
