Yo ojd does this look like what you know as the Brightside cut?
This is a photo from "of the hill", the guy that supposedly introduced Cheese to Exodus.

It certainly looks like it to me, I had the cut from Brightside for several years before some dickless fuck robbed my growshed, So I know her well.
Look for a leaf "deformity", a sort of double serration that appears on the odd "Tooth" of the leaves blades. Usually the double will be on the right hand side IME. Instead of being roughly symmetrical, on some blades where there is one tooth on the left, there will be 2 small ones on the right-this has shown in all the clones I gave to people, and I know other people here have spoken of it.
Sorry, I misread, I thought it was your picture. It deffo looks like Brightsides cut to me.
