Not that this will do much for most of you normal people...but I recently found and ordered a new GF flour through Sam's Club and have some sandwich bread going in the bread machine.
First time using this blend...and holey smokes did it rise!
Normally GF flours are heavy and struggle to get a decent rise like wheat based flours, but this stuff behaved quite differently. I followed the recipe from the maker/manufacturer of the flour mix but wowsers...I've never seen GF flour puff up so much. Of course it fell too, but not too bad so we'll see what it turns out like.
....I know, exciting, right??
