Mmmm interesting tech support, out of curiosity what loadbalancers are
you using ?

I have them too (those days), trying to ram the square block through the
round hole.... In some cases it even works :-)

You're welcome.
Word of warning: If you lose the noarp option on one of the real-servers
you will see very weird erratic behaviour which can be hard to debug.
Depending on the load you push through the loadbalancer the realserver
which sends an arp will die immediately or slowly whilst generating
weird bugs in your app.
Best way to check: login with ssh on the vip
