Never liked the Doomday Device. Always looked like a bad injury waiting to happen to me, it looks sloppy and uncontrolled. I was never a fan of the Road Warriors whole schtick tbh, the no selling and squashing everyone.
Arn Anderson's Spinebuster was awesome.
Jake Roberts' DDT is #1 for me.
Randy Savage's Big Elbow is also a thing of beauty.
Kevin Nash's Jacknife powerbomb is probably my favourite variation on that move.
Power & Glory's finisher was cool, can't remember if it had a name. The Demolition Decapitation was a cool looking move as well.
I wish finishers were still protected like they used to be.
