That'll need some planning Tom to get us all there at the same time. Would probably have to be an overnight for us as it's a good 4-5 hour drive each way. We need a resident Welsh member to guide us as well.
Snake Pass is OK but too busy especially at weekends with the bikers, and too may police.
The Ribblehead run one I've not done yet, I would think Buttertubs would be better however.
Best roads I've driven are in Wales, excepting Scottish of course which are a bit far for a day trip for us Yorkies. Did North Wales last summer around Bala and Ffestiniog and the Evo triangle they are awesome roads around there.
I do also fancy doing the black mountains in South Wales
