Thought Doug did his own tinkering? I believe this one in Vipa Miller's but they have a his & hers thing with those old P70's so someone will be able to id it:
He started the GOB match in 2008 with a Styre (thought most folks knew better than that?):
but whenn it caughed up a fur ball he finished the 2 day match with Han's "Discovery""
and still put in a good showing.
Doug & Vipa are just the nicest folks.
