Do you guys just let the air blast out when deflating the wing? Or try to do a slow deflation (not completely taking off the valve). Not sure if it makes a difference with the lifespan of the wing. Thanks!

its slow anyway..... just let air out. no issue

I've got Echo's and I tend to do a slow release for the first little bit so there's no massive pressure reduction. It probably doesn't make a difference but I feel better for doing it...

Like the others said.. Slow.. pfft-pfft.. for a few seconds then blast away.. Doing this helps prevent the bladder twisting.

Thanks everyone... appreciate the help and advice :-)
