If nobody volunteers, I'll have to do the hard work.
Cannot wait tomorrow to unpack my 15, hoping it's not going to nuke. So far, with the Sonic range, I went from amazed to ecstatic. I don't expect to be disappointed.
Regarding the Sonic 2, I'm not sure the pure performance has noticeably improved, but the handling unquestionably. It is so effing easy (disappointedly so for riders who believe they've got one of the most extreme kites available!), that IMO, it makes the Speed 5 redundant.
I've got already one question: the RACE comes with the race bar and much shorter than the ones I'm used to, I wondering about the advantages/drawbacks for a freerider.
Thank you Extreme Kites for the table I stole from your site.
