Do you have the high one, if so does it make much difference to the standard hieght one as its only 40mm which does not look much when you look at it on a ruler,as I am wondering if I need the higher one, wish I could try one for size to see

There is a high one on Ebay at the moment for sale so far £30, I see they retail new at about £85 - £90, and I have spent enough lately
