Hi to you all,
New guy #4140 here.

May I suggest you go to>
http://mid-lift.com/Choosing_EB.htm and navagate
the many pages of info at Miller Engeneeering,
for a very interesting point of view on the
rocker and its geometry. I get some of what Mr.Miller is saying but its a reach and maybe you guys will "get it".
..bye for now, Bob P.
