his recovery blows, there's not much around it, but his B^ is good roll reversal in that it's quite amazing to edge hog with it, even when you're about to be edge hogged. Olimars B^ grabs the ledge instantly, and can be used from lengthy distances, not to mention above the stage. I find this instant grapple incredibly useful in that, when you see someone's about to hug the edge (if you're in range, which you'll need to test for yourself) you B^, instantly grabbing the edge and making THEM miss. Now you're on the offensive. Also from very long distances and above the stage Olimar will do like a swing / whiplash type thing, meaning you not only steal the edge from your opponent, but you knock them out too.
Other than that I just find the B^ more useful than hugging, you get practically double the invincibility grame (while hanging on pikmin and edge), and it's the a great way to startle your opponent.
I'm awefully tired right now, so that's all the explanation you're going to get right now. Summary, the teather isn't too great of a recovery, but is a great offensive tool.
