Every time that I've used those there seems to be a stone deep down that
couses a twist. It's never near the surface where the twist could be
corrected. With about 50 cm. of fins in the ground and the stone, it's
impossible to twist it back.

Somewhere, I still have the Fensock dummy that goes into the socket
for hammering them into the ground. It's a short length of fence post
but much harder wood, with a metal cap on the top where the hammer
hits it, and a metal rod through it so you can twist to keep the socket
square as you hammer it in. ISTR it was quite expensive, but wouldn't
be hard to make if you could get a short length of 4x4 hardwood.
