Fair comment, Matt.

I agree, technically not true stereo, but nevertheless effective and that's what matters to me.

I tried PR's trick as well, it worked but needed quite a bit of fiddling as the stereo "image" was over to one side - which side depended on which way you panned the "lead" and "following" copy. In the end I used three copies of the track aligned at time 0, 0.02 and 0.04 sec and panned them in order, left, centre and right. I needed to raise the volume slightly in the track at 0 (about +1dB) to get a properly centred image. Worked and had the effect of a touch of reverb (or would it be chorus?). I'm not sure I would do it again. Try anything once, though.
