would it be good to replace the bridge pickup on my telecaster with a mini-humbucker?

Answer 1

Like everything else in music, it's a matter of personal taste.
I would not do it as 1) replacing the bridge pick up with a humbucker is not true to a telecaster's sound and2) I like single-coil pick-ups. I like that they are "alive" and that one must learn to control the noise.
