None, because I live in the people's republic of NY. However, it would likely be a Ruger MKIII or 22/45, just for the longer barrel and marginally better ballistics.
For a more "orthodox" gun, probably a Ruger SR22.
But I'll be in Florida soon... soon...
Edit: Oh, and that Heritage .22lr/.22wmr combo seems kind of cool. I see that they shoot very high though, so I dunno, that seems like the main downside to the heritage.
