Guys - seriously - why not ignore Bert?Why make a point of telling him he is not funny? Why make a point of answering to his replies?Your answers are, to be honest, only contributing to prolonging Bert's messaging.So - my advice - shut up! Wise up! Ignore Bert! and answer the question.Not sure.... I have a Concept 2 Model E. It's great, good course charting, time trials, games etc. Could do a lot worse....
