Don't forget X-men 162. While 133 and 141 were cornerstones to his coming ubber popularity, which culminated in the Miniseries, I think 162 was his first solo book. As I recall it was the first time he mentions his "Bezerker" animal part of him. To me this really made him stand out as an anti-hero and not the whiner he was under the Claremont era as well as other whining superhero's that seemed to define marvel during the 70's.
Spiderman: Whiner since day one.
Iron Man: I'm a drunk feel sorry for me.
FF: Woe is me, I'm trapped in a rock body.
Silver Surfer: Earth people just can't be nice to each other, boo hoo.
Captain America: America just isn't what it was during the war. (tears up)
Power-man: I'm Black and the man has kept me down long enough
She Hulk, Ms Marvel, Spiderwoman: Who says the weaker sex is subordinate, maybe if I beat up on enough men, I'll feel better about myself. Vote for the ERA!
Wanda: The world just doesn't understand, I'm in love with an android.
X-men: The world just doesn't understand, I'm a mutant and different from everyone else.
Hulk: Why won't puny humans just leave Hulk alone, boo hoo.
Black Bolt:
Wolverine: I'm the best there is at what I do, and what I do isn't pretty.
