The only Scopex I ever user was nashy's scopex no.1, only because mates of mine who'd been carping a lot longer than me told me that it was the better one in their opinion. The only hutchy stuff I used was his Nouville fizz, secret agent and his R.S.A. , both belters.
As Elmoputney says, Johnson Ross do some of the flavours so I guess keep an eye on their stock.
Might also be worth a check on a Facebook page called "biological bait". The bloke has untold amounts of flavours of every kind and I mean boxes upon boxes of the stuff and copies some if them so might have what you want.
