Sometimes it gets to a point where some of us don't even want to post things like this because of all the negative comments, innuendoes, and challenges beyond the subject matter.
I hope that never becomes the case Len but I have to say that some of the topics you are touching on are controversial at best. I would expect to see some turbulent responses considering the subject material. Not everyone a) understands the perspective that you bring to the table nor b) understands how some of their comments may be interpreted via written words on a page. Truth or not folks are going to want to continue to argue about issues like carbon/aluminum, mech/fixed, single/dual/hybrid, etc... simply because an opposing opinion is not what they want to hear.
