Suggestions on optimizing Spring Attack?

[Inevitability]

This might actually be the first time someone has taken a one-level dip in Barbarian, looked at Lion Totem and Pounce and said: "no, thanks, my martial character doesn't want that."

I've made a mounted barbarian who didn't take it on account of that pesky 'only one attack if your mount moves too far' clause. Plus, I needed smite anyway which meant trading Fast Movement for Unholy Fury.

Also there's probably some contrived reason why you might want to go that ranger-variant-barbarian for Rapid Shot etc? In which case it'd obviously be useless too.
