Dont be biased about Grades

Recently I read a lot of stuff on various Tea discussion groups, some undermining the quality aspect of Dust Grades. I personally do not advocate for one grade or another. Each one to his own taste and preference.
Yet, should anyone have any doubts of the quality of different grades of tea, I wish to lay down the following:-

As is known, the Whole Leaf, Fannings and the Dusts are all made from the same leaves, undergo the same process of manufacturing and is separated based on particle size during the process of sorting.
My experience is that Fanning or Dust is NEVER inferior to Whole Leaf (or Brokens in case of CTC Teas) in any way, and actually scores over Whole Leaf in terms of Cuppage and usability in Tea Bags. (4 Grms is recommended for a cup, yet Tea Bags contains 2 to 2.5 Grms only! Thats : Dust)

I am not talking here about the PULVERISED or RECONDITIONED Dust, which can easily be identified by an experienced Tea Taster.

Coming to the main point of my post, it is the process of FERMENTATION and DRYING which lends different charecteristics to different grades.

The Surface area of a grain of Tea exposed to atmosphere during Fermentation and to Hot Air during Drying vis-a-vis its mass are different in the case of different grades. As a result, the smaller grades are more thoroughly OXIDISED and DRIED, whereas the larger grades retain a bit of GREENNESS in its core.

In general, Brew Dusts for a shorter while and enjoy the flavour of Leaf or brew Leaf for a longer while and enjoy the strength of Dusts!

Tea Cheers!
