Thank you both - although in fairness to the work done by the likes of Mr Philip and Mr Dalrymple, back in the early 80's, the fact that in all this time I have had nothing more than a cosmetic issue is a lasting tribute to the fact that their work in the UK was, for its time, quite excellent.
When I hear of the troubles that some more recent girls have had with depth, sensation and other issues it makes me realise that I was very lucky indeed. But it will be really lovely to feel that the cosmetic appearence is at last on a par with the functionality.
