One thing you need to give thought to before resurrecting an old event is why we lost it in the first place - but I think you have already mentioned that increasing traffic on the roads used was a key factor.
I had a thought along the same lines, but was hesitating given I don't want to discourage the thinking on this thread. The internet is also such an impersonal place and it's possible for words to be taken wrongly. Anyway...
Before clamouring (ie putting on the peer pressure) for this to be slotted into the calendar and have the resources of AUK thrown behind it, let's get some perspective. A proud parent never thinks their baby is a dawg. I'm sure this is a bonny wee nipper sired from the loins of Jethro, but she's not even out the hospital ward yet.
I would have thought it more sensible for the first few ride reports to come through before seeking to have this slotted into the calendar. The WCW had issues and (as I understand it) was taken outside and shot for a reason.
(PS: this is in no way criticising the vision and effort of you Jethro, it's more a comment on the mindset of the collective).
