Do what us old 'uns used to do, and get on your bike, go down to the 'drome and find out!!!
Trouble with tinternet is that everyone thinks they can find out everything without ever leaving the comfort of their living rooms!
Wrong forum, I would agree. However, the argument submitted by ATNotts is is a little puzzling.
What's the internet for then? In these temperatures some may quite rightly be just a tad reluctant to get on their bike and ride (possibly a long ride) only to be disappointed. However, it might indeed be wiser for Planeaddict to ask these type of questions on a dedicated Birmingham spotters website.
