It seems to me the classical meaning of 1♣ (1♦) Dbl showing both majors is a bit space-wasting on such a low bid. In addition I have found that many WC pairs use some kind of different method nowadays? What's yours?

Mine is:

Dbl: 4+♥
1♥: 4+♠
1♠: 4♥ 4♠

I used to play Misho's "equality" after an opponents interference, which was mostly transfer advances similar to your suggestion, with some minor differences. On this specific auction, the meaning of the bids were (equality can be found on Dan Neils webpage)....

1C-(1D)
----> DBL 4+ hearts, tends to be balanced (see 2C)
----> 1H 4+ spades, tends to be balanced (see 2D)
----> 1S Balanced only (no unbid minor) unsuitable for 1NT (too strong? Wants partner to play NT, etc. may include fair club support
----> 1NT Natural, limited (see 1S)
----> 2C 5+ hearts, stronger than dbl, more distributional
----> 2D 5+ spades, stronger than 1H, more distributional
----> 2H/2S Fit jumps, this time, not forcing (see 2C/2D)
----> 2NT Really, really weak club raise, or GF club raise
----> 3C Typical preemptive club raise
----> 3H/3S Preemptive this time since 2H/2S available

More recently, I have begun to play the simplier "switch" for which Hannie has posted a nice PDF somewhere. In his PDF, this auction 1C-(1D) is not covered and switch generally is on after they overcall a BLACK suit or we open 1D and they overcall 1H (where double denies a major). So on this specific auction, I still prefer to play the equality method listed above, but currently, I do not mix this equality auction with the switch auction with any partners, so when playing switch, double is majors, otherwise bid normally on this one.

I like this:

Dbl = 4 spades
1♥ = 4+ hearts
1♠ = 5+ spades

We play T-Walsh and system on after a 1♦ overcall. This is (in this particular case ) almost identical to what Ben describes.

Mine is:

Dbl: 4+♥
1♥: 4+♠
1♠: 4♥ 4♠

Mine is similar. The only difference is that 1♠=4♠ 4+♥.
This makes it easier in competition, after 1♠ responder can rebid 2♥ with 5 (or 6).
