It is best for GIMPS to take whatever is lowest (by Candidate) to what is deemed to the optimal bit level. Then it can be released back to GIMPS for assignment for LLing.

Entirely up to you. Choosing "Lowest TF Level", and taking it up to the release level is a reasonable strategy. The current "What Makes Sense" is taking the lowest available candidate up to the release level.

At the end of the day all the current candidates need to go up to (at least) 73. Some get fixated on finding factors, and/or the "GHz Days Saved" metric so only go one level. That just means that someone else has to step in and do the rest of the work.
