Well the new boots are on and I have given them a few miles to see how they are. First impressions are that they are very quiet compared to the Duellers and the ride is a lot less harsh when going over bumps etc, at speed they feel good too. So, I am very pleased with them so far, now just need to get myself a spare to fit in the boot and that is another thing crossed off the list ready for our trip in July.

Thank you all for your advice and putting up with my, no doubt, endless questions.
