Sean If I'm reading your original post correctly, you will have an S4 chassis at your core, with G3s as building distributors and E1 switches as edge switches. Since you mention a budget restraint on licences, I'm guessing that you intend to do your distributed routing on the G3s. (Both the E1 and S4 have standard OSPF).
When I have been in a similar situation, (eg using gold DFEs as routers sans licence ), I have used RIP v2 in preference to statics. RIP is sub optimal for a couple of reasons, but it beats statics hands down IMHO. One other possibility you have is to run your load balancing on the S4. They handle this work very well, and that will certainly cure your ARP flood.

We had other issues that I cannot fully explain at this point. Our network has been very stable for many years. In essence, this NLB problem had been going on for quite some time, however with additional devices hitting OWA and our web server the problem finally hit a breaking point. The budget constraints are tied to purchasing the additional licenses for routing.

And what budget constraint implies that you must use static routes as opposed to a dynamic routing policy?

At our core we are replacing our dfe blades with an S4. Three years ago, I move all of the routing from the edge devices (E1's) to the core. Everything had run fine until an issue occurred recently. Now the thought process has been to move the routing back out to the edge devices using static routes. I am looking for external advise on the pros and cons of making this change. We have 40+ subnets/vlans. The remote buildings will have a G3 at the entrance with 2 - 3 E1's stacked behind. At some point in time, we have had up to 13K devices connect to our network.
