Looks like most other people would have done the same as you did Jane. I'm not sure I would have though. I guess it depends on how likely the 'correct' orientation etc could be achieved.
I've seen some really good re-erected stones (like the Iarsiadar Standing Stone) and those have had load of thought go into them. My concern would be that it'd end up looking very different to how it was supposed to be.
I lack BlueGloves' faith in our ability to get it right, especially with a ruinous circle. If I had a crack at it, I'd have to do a load of research first to see if the stone had been documented in its standing state.
