Favorite artisinal flour resouces?

Toast

I am looking to find sources for interesting flours.  Can you guys share some of your favorite places for ordering flour?

Many are listed in this thread: http://www.thefreshloaf.com/node/38509/where-do-you-buy-your-grains-or-flours-online

Ones I did not see on that thread:

www.centralmilling.com/store   mostly out of stock at the moment. But very educational, if you go to each flour's page and read the specs.  A connoiseur's (or flour snob's) dream. includes close up photos of grain/flour.

www.clnf.org   delayed shipping due to backlog.  Free delivery for orders over $400/$450 if you are on their truck routes.

www.brickovenbaker.com/collections/all/flour  (Caputo flours, plus GM's All Trumps)  Temporarily closed, to catch up the backlog.

www.mulinocaputo.it/en/flour   The Italian miller, famous for pizza flour.  Can't buy direct, but fun to read for educational purposes, with all the W and P/L numbers.  Very popular flour in the US at pizzerias.

 http://www.thefreshloaf.com/node/62291/experience-w-general-mills-50-lb-flour   I compiled this list of all of Gemeral Mills (Gold Medal) flours that are unbleached, unbromated, and 11% protein or more, plus neapolitan pizza flour, and 3 types of whole wheat flours.

For all 80+ types of General Mills/Gold Medal flour: https://www.generalmillscf.com/products/category/flour  --  After  you go to an indivudal flour's page, scroll down and click on the "+" next to Features & Details to see protein percent, click on PDF spec sheet (right hand side) to see ash%.  Form to find a distributor near you on right side. Some distribs will do cash sales via counter (you go pick up).
