Budlisting can cause you more problems that it fixes and I don't like it
for
anything other than a last resort.

Why not use Pre-empting on a state basis (as Tony suggested) and allow the
digipeaters to extend the paths of Mobiles and home station where more
than
2 hops are required to get to / from an IGate. Then when a new IGate in an
area is established you can turn the Pre-empting off. The users do not
have
to change their paths, it's all done for them.

In regards to the hilly terrain this may be an advantage in planning your
RF
Network. It allows you to easily create Cells and IGate Zones so that they
don't interfere with each other. You can also use fill-in digis where
coverage is bad.

I've used the natural geography of VK3 to divide our digis into cells and
zones. In most cases we have deliberately limited digipeater to mobile
coverage to roughly an 80Km to 100Km radius. This reduces the hidden
transmitter problems and increases the network efficiency. Bigger single
digipeater coverage is not always better.

Cheers
