When I saw 'shake-up' and 'closed roads' in the title I was rather worried, but seemingly/hopefully they are just going down sensible route of mainly just crossing closed public roads. Going by those comments I imagine we'll get a Penmachno that looks rather like this:

Brenig should be a massive beneficiary too, with various ways that can be turned into a proper stage now.
Got to say though that it looks like the Mahonen school of thinking will win out on one full day of Rally GB, plus probably Sunday too. Hopefully they make the more traditional long distance day in mid Wales a bloody long one as recompense! Also looks like no Thursday evening stages again, last seen in 2013, or night stages... For me ideally, with the Welsh Rally GB model, you'd run a Thursday evening loop of a Llandudno start, SS Gwydir, SS Penmachno, SS Alwen and a stage somewhere in Clocaenog. A variation of this could then be run again on Sunday morning, as has been the case for years. That leaves Friday and Saturday to be more adventurous. Makes more sense if Rally GB is running as the season finale though with this model, as you can start with Monte as a four day rally and finish with GB as a four day special too.
Only other thing, with it looking like the flawed but casual spectator popular 'RallyFest' stage in Cholmondeley is under review, it continues to be incomprehensible to me that Oulton Park Circuit isn't being considered as an alternative venue. It's the same distance from the Deeside service park as Cholmondeley and Kinmel Park, if not a little closer, and has a great rally heritage, having been part of the RAC Rally for many decades! It even hosts its own popular national rally... I just don't get it, it's not even mentioned.
