You may be correct about this. >Then he added his "mouse" to >improve the COP. I think the mouse was a first stage using his original >recipe (likening Rossi to Colonel Sanders :) ). IIRC the mouse only has a COP of about 1.2-1.6. > >Bob Higgins Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
