Final decision
Thank you to all those who have helped me and commented on my previous posts.
Narrowed it down to the Boardman ADV 8.9 and Boardman ADV 9.0. Unfortunately I don't know enough about bikes to know if the 9.0 is a significant upgrade and worth the extra cost? Thank you for your thoughts and opinions.
