Claus and Matt, Wow, you guys are opening whole new avenues of investigation. I am on it. I met a great guy this weekend at the northeast Formula championships at the SHBCC. Can't remember his last name, but first name is Mark. I think he is a past National H16 Champ. He was serving as Race Committee Chair, Boss, or whatever, and really knew his stuff. Given my rig, he thinks I may have plenty of rake, and just have to make sure that I am measuring it properly. He described the measurement in detail so I will follow his instructions and see if I have been making much ado about nothing. This could be embarrassing But I will post the results. I will also check out the points you made. Thanks again, ralph
