Tofu Todd. Glad you go up and had a good time. I am happy to hear that you had a positive experience in the Mazama Basics School. I took that class had met my climbing partners for the following 4 months of solid climbing.
Two rope teams is legit. Not everybody feels like they can learn from books alone, or have people who KNOW what they are doing to teach them. Trying to find climbing partners to teach you is a very unefficent way of doing things. If people don't like large groups on the MOST popular route on hood go climb else were. This is to be expected or go and change the number of people allowed on a climb. Yes it sucks to get behind one of these groups but if I was THAT worried about it I would not be climbing the South Side of Hood.
Tofu, climb with the mazamas as much as you want and when you feel you are ready you will solo or have developed climbing partners and head out with smaller parties. In the mean time forget these other fools.
After all it is the South Side of Hood WTF.
