We have a minimum drury call. If LHO has hearts and clubs, we have an unexpected amount of defense, in the sense that we have less than expected. If LHO has diamonds, we can double ourselves.
Partner knows on his or her own that this auction screams for doubling them. (And if partner doesn't know this, I hope I am getting paid decently.)
Agree with this. One of the reasons that drury stands out over a simple raise is that you have now expressed all of your values, and do not need to do things like double 2N - you have approximately the strength that partner expects, partner is now captain with your non-unusual hand (9 highs, 2 quicks, a small bit of distribution...this is dead average).
I think a double of 2N should be approximately 4-3-3-3 and also include something like the club Q - it should say that 1) your hand has 10-11 HCP, and 2) that partner should have a lot of distribution to compete over their bid. It should also invite partner to double aggressively with a 3 card holding in their suit. This hand does not quite meet those standards.
