To Tongue-Block or not to tongue-block?

[BEERE_MARK@xxxxxxxxxx]

Howdy y'all-

OK, so I've been playing north of 2 years, and I've never really given tongue-
blocking much more than a passing try.  I guess cuz when I first started
learning my book described it as one option to get a single note and thought
maybe it'd be a better development of technique if I could do it just with
the appropriate lipgrip (hey, a snigglet!).  Anyway, I'm wondering do almost
all accomplished players use this technique, or, except for the most dramatic
and quickest of note changes, tongue blocking is just one way to change a note?
What's the word, team?
