I use bigip even if there is only 1 machine, using heartbeat
sounds like it will make it quite a bit more complicated,
load balancers make life easier..since you already have a
good one(a pair hopefully), keep using it!

I use load balancers wherever possible even with 1 machine
so I can make changes to the system(s) in the pool without
impact. e.g. if I want to replace hardware, I can install the
new hardware, add it to the pool and remove the old system.
Of course it's ideal to always have at least 2.
