Its going to be a loose flag type one, with probably 1" gaps with small gravel in between if you get what i mean, what base would you recommend, after all the digging its basically down to the clay, currenly with a few inch of sand to level it out, then the weedblock matting. Obviouly the gravel there know will be moved elsewhere when the flags go in.
I would use 2 bags of sharp sand, one bag of soft with half a bag of cement and a bit febmix, not to wet.
Makes a good strong mix, done mine 8 years ago and still solid
