I use a fair number of non-medium monsters. It's also not unusual for me to use several types of monsters in a single night...sometimes in a single fight. So, if Im going through half a dozen monsters before every night, that's a significant amount of added prep work. As you said, it's not usually hard to figure out what they should be, but it is annoying.

And that still leaves the issue of skills, which have to be converted to the new system as well. This is particularly fun when converting over monsters with class levels, such as dragons.
