And for those who were curious about English Plaid #9 (it's not shiny):
Not sure the question is answerable...
I have a couple of David's grenadines in standard fold (ie, 4-fold), but the vast majority are in 6-fold. Both constructions are excellent but I like the weight of the 6-fold a little better and for me the extra $$ is worth it. I can easily see that it may not be worth it to others though.
When I started down the Hober journey I ordered one of each construction and decided the 6-fold was good for me. I still wear the 4-folds that I have with joy.
Don't get too wrapped up in the decision, the important thing is to select what you want, order it and then get it around your neck as soon as possible. You won't be disappointed either way.
Opinions regarding weaves will vary, but IMO one weave is not more versatile than another, it is a matter of personal preference.
Wrt timing of the restock, just email David and ask. He is great to work with and very prompt with his answers.
