Two ply warp and weft?

[Rowly]

While perusing the Huddersfieldcloth site for Dugdale-Fisher, http://www.huddersfieldcloth.com/ I noticed that the only cloths they expressly describe as being 2-ply w/w are:
The Fisher super 100's 11oz, and .....
the 120's +cashmere, 10oz.
I then looked at Harrison's site and the only 2-ply references I found were made to
Premier Grand Cru and Grand Cru.
Would it be useful to make a list of the various cloth books which are in fact Two ply warp and weft?....It might be useful for those of us who are interested in this traditional solid weave? Can anyone contribute further information on the subject?...thanks..
