Thanks Johnny - I honesty couldn't find that thread. tiem for me to start using the search terms properly!
Lee - I know what you mean and the car certainly won't be a DD or a motorway cruiser (got a hack for that) but I do have a few trips planned and I really dislike unnecessarily high cruising revs. That said, I tend to drive quite sedately on the M-way's anyway - traffic and all that lol
It's tricky because I do need to be sensible. But I think sensible is deciding whether I'm getting this done now, rather than 1 month after the conversion's finished lol
