Chances for UCs + Regular Round for CS

What do you mean by “get ready to pull the trigger on others if none come in”? While I like ASU, I would much rather prefer schools like WPI or RPI or even Santa Clara. What do you mean by “RPI can be great, but it’s very different”? Given the choice between RPI and ASU, I would choose RPI, but I’m not sure if I’m missing something.
