Hi Aquagility, I have opted for IDHI - I have based my dicision on this - If I put IDHA into google nothing comes up on the 1st page for a mountain in Crete, but if I put in IDHI there are several hits for a mountain in Crete. Also Wikipeadia lists both for the Highest Mountain in Crete. Which is why I said I thought both are correct. It is a bit tenuous I know, but I could find nothing else to go on. I hope I have made the right decision as mine is in the post now, so too late to change it. :-)
