Martin I abandoned involvement in cave map production early 1990s when it became obvious that centerline software and paper map development had outlived it's usefulness.
I have a similar story. I was overwhelmed at about 20km of cave circa 1996, and decided digital was the way forward. I then spent quite a few years rejecting all the schemes that involved propritary drawing packages, fearing putting hundreds of hours of work into some format I might never get my data out of again. Therion is indeed the 'right' answer (in many ways), although I do have issues with the time that the process/view/adjust round-trip takes with its (somewhat old-fashioned) compile/view approach. There are also some limitations introduced by the way the high-level code (therion) has limited control over the low-level stuff (metapost/PDF) (e.g. hatching when joining areas of water). However overall the system is the best currently available, so far as I can tell. One day I'll get back to the 1996 Kaninchenhohle map and therionise it, adding the 97 and 98 finds and producing the first elevation since about 1992 (when that got too hard to draw!)
