I used to use Super72 back in the day, the interlacing wasn't too bad, but goodness knows what it did to my young eyes!
I believe the best resolution you will be able to achieve will be DBLpal - play around with Overscan preferences and MonEd to increase the visible area. However, be warned, the poor refresh rate is likely to give you a pretty awful headache after looking at a CRT for any length of time.
Good luck,
James
