Also from the eZine it says this which reflects on my earlier thought about which fx to upsample or not.
"A new option in the plug-in window’s System Menu (click on the button in the plug-in window’s upper left) specifies whether a plug-in should be upsampled to a higher sample rate when........."bouncing, rendering, freezing, exporting, etc. This option persists globally for all instances of the plug-in in all projects, so it needs to be set only once per plug-in. It can also be disabled at any time."
