I give the actual bidding but consider S playing 4♥ (or 5♥ but trying to gain some MPs by only going -1).
A club lead is fairly awkward, say declarer wins then ducks a spade and W returns either his second club or the K♦. You win the return and draw trumps finding W has 3 along with the probably 7 spades he's shown in the auction.
Now you rumble 5 trumps and reach a pleasingly symmetrical pair of end positions: (E can't discard a club or you simply establish dummy's 4th one so his discards are fixed)
If he returned a second club:
If he returned K♦
In either case you now cash your final trump, throwing the suit of which dummy has 3, and E has the choice of discarding from the suit of which he has 3, in which case you play 2 rounds of that suit and endplay him for 10 tricks, or discard from his doubleton and get thrown in in that suit for 11.
