....to add to foot switch advice:
Back foot push-down just as switch is initiated works well for me when switching heel to toe, however I can't do it (yet) when switching toe to heel. In this case a extra lift from the kite makes up for it.
So if having problem with nose diving during the foot switch, pay close attention to your kite flying during the maneuver. You still should to be quick but extra lift from the kite makes it less critical.
Gunnar has a great video on the topic here: http://www.youtube.com/watch?v=WPH31Z2uqvs
My initial try’s of pumping. With 90cm mast and kite.
Seems to indicate that pumping with front foot bias is like stomping on concrete while the best drive forward was achieved using even foot pressure.
But even that was a push down with lots of resistance then a surge forward.
Done with kite drifting backwards and zero line tension so not time to keep pumping.
Is there something I’m missing? This pumping thing is a whole new thing for me and my only experience is the Spitfire. I have at this point no geriatric foil to compare
