I have enjoyed your pics and narration, been on most of the routes you have done and always meant to do a report like yours, but I find the scenery and riding so enjoyable I don't want to stop. I might just try one on my next outing.
Here's a wee link to a vid I made recently heading to Aberfoyle via Thornhill, Lake of Menteith, Dukes pass, Callendar, Doune, then back home to Bonnybridge.
The quality could be better. http://www.youtube.com/watch?v=_WnjnIMiRyk
Good luck with the bike test.
