Whoa...What a Big 'ol Can we opened up here. I am absolutely thrilled about this dialogue. Thank you. I value most opinions so far. Some of my favorite advice has been from 'spotly' and 'mattp' Thanks a lot. FYI all- I do have a fair bit of judgment from soloing other places along with a fair bit of glacial navigation and crevasse rescue training. Having never set foot on said mountain, however, I'm using this forum to probe a bit more than: 
-my ego, judgment, experience can give (over-confidence? or correct competence?) 
-my Rainier exp. climbing buddies' encouragement, 
-the books can tell you,  
-the rangers and nasayers say, 
-what some dude at the bar sprays at you 
  
It'll be really fun if/when I actually do it (with or without a team) and take a look back at what people said to see what made sense.
