Hi garry p

The CSA 2004 guidelines states their are certain circumstances when these knobs may be used. I agree with everything you are stating however if you go by the 'experts', apparently, following these conditions, it is fine.

I still prefer using the steering wheel however I do have a client or two where the steering **** does make sense, proided that it is used accordingly.

One of my students last week had it flung off the wheel becuase it was not mounted properly. No one was hurt nor was anything damaged. Just an inconvenience.

Everybody has their own opinion about this and many other subjects however paul c is lloking for a rule and the CSA guidleines do have the rule.

BTW, long time, no speak.
