I'm hearing you Nazzy. It's reset time...
Gents, all of you in the last few posts, thanks very much for the detailed suggestions. It's given me a heap to work with and permission, if you like, to experiment with something beyond the "arse out, sit back" paradigm.
It'll take me a while to build up the flexibility and strength to be squatting anything half-decent again, but I'll make better use of the camera this time around, and try not to waste another year.
