Excellent work Nut. Would you not just treat it as a gooseberry?
Edit: "Ribes speciosum can be treated like a gooseberry, which means pruning away half of the length of shoot that grew the previous summer. This is done in winter. The side shoots, which can be cut back to about 4in, may also need to be tipped in summer. You can even clip it like a hedge. It does not need a sunny wall or fence, but give it a bit of height and allow it to get quite tall, because it will look terrific at this time of year."
