Bo skeletons or not depends. Most people will tell you to have a skeleton BO because of limit of displacement left.
Ironically, it is most of these people, that do not bother trimming their torpedoman since they are easy to cap. Trimming them, removes a huge amount of weight.
Now, if you were to delay an Ellite repairman as a torper, best advice is to class it in the late 100+ or 120 if you are hardcore. That's where you get an interesting repair effect.
If you're going to delay something, do it right, else, your crew won't be better than some class on time.
