Hey justin, i have the same kite and was after the same info, cheers. Also have you seen the "smart loop" for the naish? Do you know if we can retrofit this system on to our kite, more user friendly, google that one, cheers.
Yes you can retrofit the Smart loop to the Shockwave, it's just a little bit tighter fit through the bar.
For replacing the bridle make sure you buy the decent stuff if going to a chandlery. You could also buy some bridle line from your local kite store or a replacement Naish bridle (more costly though)
