my gen'l approach is 2/1 ... what is the best way to bid 6:4 distributions?
what is best with a good six card suit . . . and a so-so 4 card suit?
what is best with a bad six card suit . . . and a very good 4 card suit?

It depends. I assume the 6 card suit is higher ranking than the 4 card suit.

With 6 spades and 4 hearts, its generally best to always show the hearts first (example: 1♠ - 1N - 2♥)

With 6 major and 4 of a minor, the typical thinking is:

---With a minimum, rebid your 6 card suit (1♥ - 1♠ - 2♥).
---With a maximum (where you can justify 3 calls): (1♥ - 1♠ - 2♦ - 2x - 3♥)

When the 4 card suit is higher ranking, its customary to rebid the 4 card suit if the rebid is a non-reverse.

Many years I was confident that it is always better to show the second suit if possible. The idea is that pd know knows 9 cards from you and not just 6.

But espacially at mps I now tend to rebid my good 6 card (major) suit, because soemtimes even a 6-1 fit plays better (or at least counts more) then the 4-4 fit in the minor.

The short answer is: always make the most economic bid, i.e.
1♥-1♠
2♣
or
1♥-2♦
2♥

By the same token, if the hand is too strong for a non-forcing simple rebid of the opening suit, prefer a reverse to a jump rebid, i.e.
1♦-1♠
2♥

But not everybody agrees with this. Some prefer always to rebid the opening suit with a minimum. And some believe that a reverse should promise more strength than a jump rebid of the opening suit.
