(Spoiler?) Heroes must die on all runes

[Findus]

Im trying to do heroes must die with all runes, but its difficult to kill the hero since he not only has really high HP. Perhaps more importantly he also regenerates his health much quicker than any of the otherwise succesfull combinations of traps can deal. Snares also dont deal enough damage, infact they only slow him down giving him time to heal between each trap.

Any tips to killing him off?

I did it easy with springs and spin traps plus trap booster.
