Cheers robbo,
that was the ticket allright.
Mistakenly I have been pulling on the power leading into the jump to get maximum oomph (and of course the kite flies back in the window) so when trying to send it up and release I have been screaming down wind.
Tried letting out the bar before I was sending it and then pulling in slightly after or as popping it - Hey Presto - going up; 4th floor ladies lingerie!!

Straight up then waited till nearly at apex before bring kite back around. All good and much more controlled. Tops feeling and mega height with less drama

Pity the wind died on me after on 2 jumps on Tues night. Bizarre conditions.

Later that night I found myself reading a Thomas the tank book to my 4 yr old and in the coastal background behind Oliver (the great western engine) I noticed a couple of sailboats and couldn't help but think mmmm they're arent keeled over too much so maybe get the 15.5 Flow out...
My young lad just doesn't understand why I drift off mid story with a far away look in my eyes
