For your own benefit I would test on your own a client in the low mid and high level of roaming agressivness, so you can see for yourself.
We have our 2,000+ clients on the Intel with HIGH aggressive roaming and they work well. I did some testing with clients on mid and low and they didn't to bad either.
If you have clients jumping to quick then you may want to tune it down.
