I use:

3♣ = Stayman (not puppet). May be bid with a minor single-suiter (bids 4m next or 4♠ with diamonds over a 3NT rebid, where 3NT shows both majors).
3red = Transfer
3♠ = Asks for a 5 card suit, slam interest (usually balanced). If opener responds 3NT (no five card suit) then you bid 4 card suits up the line ala Baron.
3NT = To play
4m = Both minors, slam interest with better/longer suit
4M = Natural slam try, forcing
4N = Quantitative
5m = Natural slam try, non-forcing

Kungsgeten,

A most interesting method that appears to be quite good, but could you clarify the 3♣ description, I don't quite understand the 4♠ with diamonds bit.

Sure, here's the full scheme after 3♣:

2NT-3♣;
3♦ = No four card major
...3M = Smolen
...3NT = To play
...4m = Natural slam try, does not promise a major
3M = 4 card major, not the other major
...Other major = Slam try in opener's major
...3NT = To play
...4m = Natural slam try, does not promise the other major
...4M = To play
3NT = 4-4 majors
...4♣ = Natural slam try
...4red = Puppet to 4M
...4♠ = Slam try in diamonds
