As a biased and huge fan of Shield/SS I have to say there are few things more satisfying than Shield Charge + Foot Stomp + Mighty Judgement triple combo.
I love my Fire/Fire tanker, and while FSC is fantastic it just doesn't *FEEL* as impactful as Foot Stomp. Additionally I recently started a Shield/Electric tanker to play around with the Shield Charge / Lightning Rod combo which also sounds crazy fun, although I hear it is a truly special combo for a stalker as I heard it doesn't break your hide.
