I used an Assy. in a sleeve, which done a good job going down wind BUT
when I got my 170% drifter it sure limited the Spinn. use.

I fly the Drifter Free behind the Furler. I can work up-wind, reach and
downwind I can go Wing-on-wing with both Drifter and genny poled out.
Almost as good as the Spinn and 10 times easier.

This ismy prefered light air rig for just knocking about. If I have a
long trip on a reach or downwind, I'll use the Spinnaker

Works for me.
