I was apprehensive at first, but it is a lot easier than you think. With just a couple of test negs under your belt, you should be able to judge proper highlight development with a decent amount of accuracy. You can always use the time & temp method at the same time, just check to make sure they're "done" before you stop them.

Take Jim up on his offer to help. These are important negs to you & DBI is a good tool to be familiar with anyway.
