I'll go in order from who I first got into..like a timeline:
1. Piper: He did it for me in the 80's man. He was energetic, charismatic, crazy, great stick work..Piper's Pit was my fave segment. Many memorable moments from that segment. He was my fave wrestler for a while, and the reason I got into the wwf. Always wanted to see him beat Hogan's ass.
2. Bret Hart: Liked the Hart Foundation, but was more a fan of the team and not a single wrestler..that all changed once Bret became a singles wrestler mostly..I once liked him, and then grew to love him, in a very heterosexual manner mind you

..his matches were awesome, and he just got to me..it's hard to describe.
3. Owen Hart: He is tied with my next mention, I started liking them both about the same time really..Owen when he came forth as that whining younger brother just made the next few years watchable for me, as that was the feud(him and Bret) that kept me riveted. I dont think anyone has played that jealous, whiney, heelish sneaky character better then owen. Really good heel imo. And he could match Bret pretty much in the ring.
4. Brian Pillman: Reason I watched any wcw at all. Liked him from the get go, but then seriously started to love him around 1995..when he and his charcter evolved into the psychopath. Performed the greatest shoot/work angle in history imo, and was great on the mic and in the ring. Shitty ankle injury from a car wreck fucked things up in the end unfortunately, but would have been big time had he lived longer. Was my fave wrestler with Bret at this time.
5. Steve Austin: Always a bit below Pillman for me, but I liked him alot. Became a guy I couldnt wait to watch on tv in 1996. His KOTR speech is forever ingrained in my wrestling memory log files. He was just oozing intensity.
