My Note 2 has a 2000 PRL also. I've read that across the nation people are complaining about this PRL. I'm rooted, so I could switch, but I've seen a difference really when switching. (Except in Chilis in Rancho)
I also read this from someone that knows about these things, "PRLs have no affect on LTE speeds. The only time a PRL will affect LTE speeds is if you write one that has no enabler record for your area and that will prevent your phone from connecting to LTE. So in layman's terms all there is an on/off switch in the PRL for LTE, nothing more."
