Naish trip is a really amazing kite! I think they launched it to early as the kites hydrofoil weren't so famous a the beguining!!
I bought a 8m 2015 (i think... blue and white model) new and really cheap (350€) and this is by far the best kite i tried for freeriding / wave / freestyle riding!! this is my biger kite, i'm out on it around 9/10 knots, so stable even in gusty shity winds, relaunch really easyly puling 1 back line or reverse launch in really light wind, it's so precise at the bar and it stay really stable at any place in the wind window. i even used it few times with my surf in waves and works great (super drift) but a bit slow in waves for my taste (wich i liked on my foil).
befor i had a 9m Gong strutless and i didn't like it, less high end, to "racy" for my taste, not a grunty kite and it accelerate non stop when you are riding...
for me the big difference with between the trip and Gong are : Trip is an all around/wave strutless and the Gong is more freeracing strutless kite
For me the Trip was the best by i did in a long time
