I watched that. Looks like they're planning to run classes generally aligned with the nationals (Pro/Am 600 and Superbike plus a lightweight class (probably Pro and Am on track at the same time) plus an ... erm ... "vintage rider" class, which I'm speculating would be run what you brung.
I'm watching with interest but no commitment, depends how certain things shake out. Not a fan of driving that far and back for a one day event (which would still require an overnight) especially if I can only practically run one class. I understand that it's together with track days. If there's a track day before, that could be used as a practice day, that interests me more, but ... and it's a big but ... for the lightweight race bikes (me), that track day cannot work out as per the last Pro 6 track day that I did (in which I was put into the intermediate group and essentially forbade from overtaking anyone under any circumstances *). That is not happening again. Either lightweight race bikes get their own session (best choice, but it means Pro 6 would be running four groups rather than three), or allowed out in the advanced group (not a fan because of speed difference on straightaways, and I understand that Pro 6 is not a fan, either), or if we are sent out in the intermediate group, *some* sort of allowance is made for overtaking (and I'm not a fan of being out in that group at all). If there's no allowance made for lightweight race bikes, I'm out as far as track days are concerned. If that results in it being a one-day event (because I have no interest in a track day in which I'm placed in the same situation as the last one that I did), then I'm out.
Point 1: at SOAR practice, I go out with the Pro group, and I'm the slowest thing out there, and it has never been a problem ... but that track has nowhere near the speed differences and blind spots that Bogie does.
Point 2: The best track-day rules that I've seen: Instead of our different-rule-for-each-group, only allowed to pass in certain places, etc., the other arrangement was same rules for all groups, do whatever you need to do in terms of passing, but you have to keep 2 metres apart from any other bike. Little did we know at the time (November 2019) how relevant that 2 metre separation from other people would become ...
* The problem is that although I'm technically allowed to overtake on straightaways, with 42 horsepower on tap, that is physically not possible, and the only places where I could overtake (often quite easily and still maintaining 2 metres distance), it's not allowed in the intermediate group. "Just pull into the pits and go back out to get away from the other bikes" - just results in the same situation happening someplace else, frustrating, it meant the whole day was a waste of time, money, tires, and wear and tear. What actually did work, was going out on track first with a few seconds gap to the bigger bikes; if they were able to overtake before corner 5 then that meant they were legitimately faster and were not a problem, but this gap prevented the slower riders on bigger bikes being able to catch up on that straight, and if they didn't make it past by corner 5, they weren't going to. But, this only worked the one time by coincidence. If it were organised to happen that way, it would make for a better experience ...
