I don't see a way of incorporating FL sizing with a collet for the neck like Lee uses.
The next best thing I know of is using the Lee collet dies with Redding Body/Shoulder dies. They do require lube, but you get all the benefit of the Lee collet along with body sizing and shoulder bumping without messing with what the Lee did to the neck.
Still happily answering to the call-sign Peetza.
The problem, as you so eloquently put it, is choice.
