Quote - And a good plan, at that.  That makes sense.  Although I can see the benefit to a checkbox option for one off items, I wouldn't put it as a high priority. 

I forgot to menton: it's not just a checkbox - you'd also have to set the thickness for each material too (and remember what the right value was every time!). Another reason it's easier to do via a material preset.

I'm sure the material wizards here will post a few 'double-sided materials'  soon enough :-)
