I seem to use the 6 thou one the most.
The other thing to be really carefull of is to only use the same brand of shell holder with the dies.
This i found out the hardway by mismatching and rendering a heap of good brass to the bin when I started getting case separations from it been oversized.
I will try to find the link to the pod cast as its bloody interesting.
I even bought another set for my 300 norma mag, not cheap but by far the best option for achieving correct head spaced brass.
Just saying

Sounds a bit spurious. Almost like they're trying to get you to buy their shell holders. Whether you adjust the height of the die or use a different shell holder to adjust the height of the case, surely the end result is that the case gets shoved the same amount into the die, no?

The standard plate height is meant to be 0.125" though sticking with only one shell holder is not a bad idea, since you cannot trust that they'll all be exact.
