In WPX, the only cut numbers I used were leading T's. However, there
were times that I felt like not using cut numbers was excessive /
discourteous to the other station -- the "when in Rome..." phenomenon,
I guess.
Personally, I didn't have a problem with leading A's and T's, or
trailing T's and N's when the signals were strong. A couple of
stations used cut numbers "in the middle", which I found a little
headache-inducing.
When responding to a repeat, or when sending number 599, 1599, 2599,
etc., I think using the full number would be better.
