Looking for a 5M Core GTs.

That'd be in the angry wasp section of buy n sell
strange choice if you don't mind me asking, you'd need some very solid wind to get it to perform

An excellent kite! Bought one of SeaBreeze several years ago. It really is tough as nails. Great in anything over 20 knts on a surfboard. Currently still flying it, however want to see if anyone has another.

Bit more chance with a 6/7
or hit up action sports balcatta , they might be able to grab a superseded 5 for you, worth a shot
