I run Pagid yellows, and yeah, they love to squeal when they're cold. Cold, as in, like you said, not at track driving operating temperature. Occasional street driving is loud, but I don't concern myself with that.
Not only is the yellow pad performance better at the track, but they are Pagid's "endurance" pad, so, at least compared to stock, they last a good deal longer too. Performance and durability are easily worth a little noise to me.
Pros: good performance, long lasting
Cons: squeals when cold
