Growing gooseberries & red/black currants - bushes vs cordons?

Evening all,

Poundland are currently selling the above in bare root form for... £1 and I did get a few but I was wondering if it is worth investing in a few more but this decision relates to the following..

My aunty has planted 4 fruit trees in two different big patches and I would like to utilise the space between so I was thinking of using one patch as a 'forest' garden style fruit patch.

The other I am either going to do the same or I will try to grow the above in cordons just to see how it goes.

If I was to try growing it in cordons would it/could I fit in more plants as opposed to growing in bushes (thus I will be in poundland asap again)? Are yields increased?

How would I go about doing it?

Thanks for your help,

Samuel
