Sam,
I think you are right in the range where you want to be ... you can
move the size of the PAJ2 up or down to make finer adjustments. You
can then adjust you slide needles with confidence ... I would think
you would want some "color" on those plugs Sam ... not too clean and
white ....... IMHO of course .....
