Hi Davor,
yes, I think you will get with the VMG2 most probably the best high speed kite you could get at this time. The speed and flying stability are awsome - this kite was designed for winning races and not for my playing at the beach
which was just to report a subjective impression from a non pro racer. I can compare it a little bit with the Sonic3 - the VMG2 is definitely faster and goes more forward to the wind window - this was clearly to recognize - even for me. And it was really extremely stable if it flys through the wind window.
I m sure you will love it in buggy if your focus is to increase V-max and go upwind faster...
