In Clojure, Is it idiomatically correct to use require ... as rather than use... in the ns macro

I'm writing a clojure application which is growing from small to medium sized. We're currently importing modules using

(ns foo (:use bar))
(fn-in-bar)

but I think that switching to

(ns foo 
  (:require [bar :as b])) 
(b/fn-in-bar)

would help with clarity and code comprehension. Is this a good way to do things? Is there a better way?
