I had a slider style all last season and it was perfect.

It is pretty snug and not likely to ping open unwanted (unlike the predecessor I had - a double layer velcro release ).

Early on with my new kite/safety leash set-up I got into a situation where I had to bail and release the kite deliberately (had already stuffed my foot from a wave driving me down onto reef and about to cop the 2nd sizeable wave right on the head) the sliding release worked perfectly and super quick.

Sorry but i am a fan of sliders. The good thing in a pinch is to find the clip/harness ring so easy and just slide your release straight off from there.
The unreliable velcro leash I had previously was not super difficult but required a fair bit more time/co-ordination to locat the velcro lifter. In some cases that may mean fumbling or taking yout eyes off the kite/situation to look at the release.
TIME = GETOUTTATHESH!TLIVETOSEEANOTHERDAY I reckon.
Two thumbs up for snug sliders I reckon.


So easy to release when you want to but not prone to release when you don't.
BTW - I check my release every few weeks but don't make a habit of undoing it a lot as that may stretch the fit and lead to accidental release.
Hey Charlie I had 2 slightly diff Airush leashes and one was a shocker (er.. 2006-2007?) but they next one wasn't flash either.
The velcro numbers do take more luck or co-ordination to get free than a slider and if your getting rolled in a wave or similar you just wanna be able to release as easy as poss.
