grigri's are commonly seen on worked single pitch sports routes
seen some near misses – (but also with other devices) – but with grigri easy to be complacent with them and develop bad habits and what you can get away with varies by rope
http://www.petzl.com/en/outdoor/belay-devices/grigri includes a video
not from Evesham but have a mate who lives near there – theres a toproping wall just opened in the new leisure centre – down by the river somewhere

Yeah I've seen all the vids and read all the bumf on grigri's and the leisure centre is where I've been going.
