Thanks for posting that. There's another reason to use an RSL. Funny how people think they're too good to need one.
This summer I saw a very experienced jumper jumping a moderately loaded nine cell have a partial collapse, 180 turn and reinflation at low altitude due to wake turbulence. Maybe this is an issue that needs more awareness. The strength of wake turbulence is influenced by several different factors, and so are our canopies' reactions to it. Our modern canopies have little tolerance for many things. Wake turbulence might be one of them.
