Because the hurricane has 2 choppers and the thunderbolt and model 2 have one. That's why a dual tone thunderbolt doesn't seem as potent as a dual tone hurricane. Too bad nobody seems to own a fully functioning mkII hurricane. It would be fun to do a shootout between that one and the bolt. Anyways....

The one near my was one of the very last ones to get replaced with a ASC T-135 AC/DC siren. Most of ...

Why a T-112? Why not a T-121? A T-112 is basically a T-121 minus the horns. They were replacing the sirens with those of equivalent range.
