    Description
We present an update on efforts to reduce the radon 
induced background in
the DRIFT-II direction sensitive WIMP dark matter detector 
and the
implications of this for improving sensitivity to spin-
dependent
interactions with a galactic directional signature.  New data 
including
operation with a fluorine target is presented along with 
concepts for
scale-up to a new 24 m3 experiment at the Boulby 
underground site.
