I am currently using BondEdge for portfolio level analytics, but I hate it. It crashes constantly, doesn't handle hybrid-arms the way I want it to, and is about to go way up in cost. Does anyone out there know of another software package that works better? I'm especially looking for portfolio-level scenario analysis and it has to work with munis.

Citi's Yield Book is a good product. Get a 30 day trial and check it out.
