i will have to think about this after i sober up. before then i hope cliff gets involved and irons it out with rtiger2. sadly, i don't think cliff has actually put any of the busses with corrugated bevels through testing so it will remain a theoretical argument. i do wish we could see two otherwise equivalent blades (one with and one without the bevels) put through the paces of some semi-scientific testing on which comparisons could be more practically based...
