Here is a 24 ply result with Rainbow Serpent. This is a little better then before when it took 78 minutes but of course can't compare with how easily Spark can solve it.

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.
