I went on one of those last year
Don't know how much the different courses differ, but the one I was on had numerous ziplines. I don't think I made a successful landing on any of them. Even when I thought I was coming in for a perfect landing, feet at the ready, I promptly went arse over tit and ended up, as wookiee puts it, with a woodchip wedgie.

when I was in Spain last year I went on a zip line thing over a big pool,
but there was no rubber left on the handle so it was really slippy and as soon as my feet left the ledge I slipped straight off and back slapped the water. Sank like a stone. It was so fucking painful, I was at the bottom of the pool for a minute before I realised I was still underwater.

But at least you didn't end up with an arse full of woodchippings
(Ouch, all the same, that must have been nasty...)

I've been to two, and they're mostly the same, just differ in height and length of ziplines.
The last time I went I managed to get a perfect landing every time. My lady, however, managed to somehow flip around the wire and end up faceplanting.

Ouch
And I thought it bad enough having to pick woodchipppings out of my pants.
