As far as I know 7's don't do metal ones Ricky
The only people that did ally ones were the new Powerizers (few proplems with then I heard
)
I have 4 sets of Cuffs (one on each set of PJ's
) and they are all held on with the PJ plastic ones and so far I've not had one slip or move even when Chocl8 was 8ft in the air and doing backflips on them ( that still haunts my dreams
the fear of someone doing that on something I had built
)
So I would just call PJ and use them
