Iv'e had a fly of the Argo 7m, it's a well balanced unit in strong winds, works well as a wave kite.
Mark Barnett was here with the TRX 12m last week, didn't get a chance to fly that one but it certainly worked well for him in litter winds down the line, looked quick.
Sounds like the TRX is designed more for waves. Maybe we will get a demo sent this way?
