I have the UK Halsey genoa (shown below) and it works well. I would think North can do the same -- I use a North 3DL on a continous-line furler (#1 genoa for light air) but of course that isn't reefable and it doesn't have the extra reinforcing arrays.

Both companies make nice sails, but overall I'm a little more impressed with the shape of the UK Halsey even though the North 3DL is higher-tech construction.
