Hi Navin,
Its my opinion if you start getting fancy with changing romaing you will ask for even more problems. If the network is properly deisgned and a soild survey was done you shouldnt have to get fancy.
A few quick questions..
1. Why the L3 roam ?
2. Is there proper cell over lap
3. What model phones are you using
