scale / base-scale question

Adding in the "break"s within the maps worked well, thank you!

Now I have another question to do with scaling...

I want to print out the final survey at 1:500 (to be consistent with other caves in the area).

However most of the cave passages are between 1 and 2m wide.  I have noticed that you use 1:200 for drawing up passages of a similar width, and have therefore the symbol sizes have been designed accordingly.

I tried several different combinations of scale and base-scale options, with the following results:

1) scale 1 500
* symbols (water and air flow arrows especially) are disproportionately large for the passage, the arrow heads of the water-flows are often larger than the passages they are in
* wall lines seem very thick, and overshadow the smaller passages

2) scale 1 500
  base-scale 1 200
* labels are small (but I can change that easily enough with the "fonts_setup" thing described in The Therionbook)
* water-flow arrowheads are all wiggly rather than triangular
* air-flow arrows and other symbols are great

3) scale 1 200
* symbols look good
* but at 1:200, not 1:500, perhaps I could scale it in a graphics package before printing, though this seems like cheating!

Any suggestions for how to create the best output?

Thanks,
Jenny
