Thank you for all the comments.

I bid 4H and doubled 4S, -790. Those that cue first will probably do better, partner will feel invited to act and you can escape for -300.

Without the double we play that 2S is a cue for hearts and 2NT is natural. After the double I think that 2S should be natural and 2NT should be a heart raise, with the balanced invite you can redouble.

Playing the normal English defence to a Multi, partner isn't particularly limited - just the same range as an overcall over a natural weak two. Some people play that all hands with 16+ start with a double, in which case 2♥ is limited. However, playing either method I'd want to involve partner in the decision about what to do over 4♠.

On the next round, if I'd shown a limit raise or better, and one of the opponents bid 4♠, I'd double to say that I had more than what I'd already shown. Unless I could make a forcing pass, of course.

The "normal English defence to a multi" is Dixon where a 2H overcall is not natural but rather a (limited) take-out of spades with at least 4 hearts.
