What planet are you guys on...
I think we are way too critical of our commentators. To my mind Diffey overcame his natural exuberance to become a pretty informed commentator. No wonder the yanks love him as he would be a cut above most of their guys - former racers included.
I don't think we have too much to complain about here on Ch 10. Bill Woods is remarkably good for a generalist, certainly miles in front of the recently departed Matthew White. Also I think Greg Rust is pretty competent as was Grant Denyer.
As for the ex-racers; no complaints re Crompton and I think that Beattie has improved out of sight.
Now if they could just give "occasional interviewer" Mick Doohan some pointers - he really is cringe material at present, unfortunately.
