OSPF Routed Network w/ roaming?

I'm wondering, I want to switch to an OSPF routed network, and still have seamless roaming between AP's on my network, currently I have about 13 APs (sectorized, some cover 240 degrees, others 360). I've been thinking about this a long time, I have an all IP network, and either I would use IPIP or EOIP from my main router to each AP, but last time I used EOIP, I had problems routing to the same subnet from another unit. But would I be losing any gains I have by going to a bridged over routed network? I mainly want to have self-repair on the backhauls, and everyone says routed is so much more efficient.

Is this the way to go? Are EOIP tunnels more efficient at knowing where a particular MAC address is vs bridged, or is it just the same thing?

EOIP tunnels will become ports of a bridge, just like physical interfaces. It's the bridge that needs to know (learn) where (behind which port) a MAC address can be found, so EOIP does not make bridging itself any more efficient.

Well isn't some of the reason for switching from bridging to routed to reduce the amount of inter-node broadcast traffic, right? Also to drop the number of duplicate transmissions across the network too? Now let's say I disabled all broadcast MAC and IP at the tunnel AP side, and used proxy-arp from the other side - but in reality I could probably do that on a bridged network as well.
