From Lokari's tailoring guide (
http://www.lokari.net/everquest/cult...teelsilk_armor - last updated March 4, 2004):
Steelsilk (non-imbued) has trivials >165 while all the imbued stuff is <135.
This site (
http://eqruckus.tripod.com/cultural_tailoring.htm - unknown update date) both supports and adds info:
Steelsilk (non-imbued) has trivials >170 while all the imbued stuff is <=119
