Razorback DBC

Winner on a loser and dinking the defense in the same hand I held: Q J 9 7, 10, K Q 4, K 10 9 6 5. LHO opened with 1H, and the bidding went: 1H, dbl, 2H, 2S, 3H, 3S, all pass. Partner came down with: A 8 6, 7 2, A J 8 7, A Q 7 6. I got the expected heart lead and heart continuation. On the face of it, I have five club winners, four diamond winners, the spade ace, a heart ruff, and one trick from the Q J of spades for a total of twelve tricks. But what am I going to do about those six trumps the defenders have? First I played a winning club on the second heart. I ruffed the heart continuation on the board, and led clubs to dink the RHO, ruffed the fourth heart on the board, played the ace of spades (spade 10 from RHO), and dinked RHO again (spade king J). I won the continuation, pulled trumps, and claimed three. At the other table they were down several at four spades. I think five clubs is cold, but could we get there? Perhaps: 1H, dbl, 2H, 3C, 3H, pass, pass, 3S, pass, 4C, pass, 5C. I think this would show a hand with game interest, five clubs, and four spades.
