i m still using a synergy 12 for snow and water in the Alps (gusty winds most of the time....)
i don t have many flat areas and the kite is good at kitelooping for climbing hills.i m selling mine and going to flysurfer ( the new unity), my elbows can t work those PL kites much anymore, i need a more park and ride kite... ( i won t say grandfather kite....), i might have some disapointment on the turning speed...but well.. i will see...
u can find many cheap LEIs. less handy on snow , good depower for gusty inland winds.
on my spot, a bunch of them blew out on ice shards and undersnow tree branch and barbwires tho. try to check one that have a good reinforced LE ( like the bularoo or else)
