	You may be able to tweak this by setting:

router bgp 1
 bgp always-compare-med
 bgp log-neighbor-changes
 bgp deterministic-med

	Verio and Sprint allow you to influence your traffic by
sending them communities.

	I would suggest asking your other provider if they have similar
communities available for use.  This is probally your best bet for
managing your traffic patterns in an inteligent and effetive manner.
