not to be a party pooper, but what you get is what you get.
There are many, many variations from brewing place to brewing place. do you know how different some of the pu I brew tastes when I brew it in your house as opposed to when I brew it in mine?
Also, don't forget the unique palate of the taster.
The Da Yi Hong - I had the raw version of that, and while this may not help, it had a good bit of flavour, and limited bitterness, even when pushed a little.
For the Mengku - I haven't tried it, but Hobbes has written about it, and perhaps some other readers have written about it as well.http://half-dipper.blogspot.com/2008/04 ... u-001.html
The Jade Dew - look at some things on that one. it says premium, which may or may not mean that it uses smaller leaves. looking at the photo- it's hard to tell. the leaves look big-ish to me. There's a flavour difference between the small leaf shu pu and big leaf shu pu - like the difference between the dayi 'wu zi deng ke' and the dayi 8592.
all I can really definitively tell you right now is to try, try ,try new teas!
best of luck!
