The Canadian Destroyer (flipping piledriver), is my all time favorite finisher in any wrestling show. I'm very happy Little Petey Pump is back in TNA, I get all excited every time I see him hit his finisher.
I concur with Benny by listing the Canadian Destroyer as my favourite TNA finisher ever. I remember the first time i saw it my mind was absolutly blown away! It's an amazing move and was pleasantly surprised when he recently returned to TNA.
