Well, you are right!! Why even use distribute-lists in the first place? Route-maps are more flexible... He can even match as-path 1 and set the filter-list to ^$. This way, in case he has to advertise networks in the future, he does not need to worry about adding it to the acl..... And for outbound, prefix-list/distribute-list takes precedence over a filter-list over a route-map..... And since this is 2 different ISP's, I would just load-share the traffic for outbound and inbound... Prepend out one ISP for Inbound and set the wt. in on the other for outbound..... Or he can also just set 2 static default routes out with one having a higher AD.... This way, he does not have to depend on the ISP's for the default - more control..... Well, that's just my 2c ;->
