I've had an Boxer SLE and an 08 Cult. I have had the following happen. The Bridles on both wore out and broke, I made my own out of 3mm Spectre and it cost about $15. I blew the strut and bladder on my SLE and logic dictates that if you slam the leading edge you can over pressurise the struts particularly if you only let the LE down after each session. I also broke a Smartloop, the bolts rusted out and the plastc sleeve exploded. However there are two reasons I will stick with Naish; the first being that the kites fly well, have light bar pressure and do everything I want, the second is the amazing service I have recieved from Glen at Xshore, JB and recently, Aaron at Windgenuity. If I have any problems with the one pump I'll just pull the one way valves out, it will make it easier to deflate anyway. In saying that the toughest and most well built kite I've seen is the Flexifoil Atom.
