Helistream also had a R22 IFR trainer, many moons ago when I flew with them while in the LA area.
chris-tt, don't fret the thunderstorms in Florida. It's common to have convective activity when you're in an area with heat and humidity, and afternoon thunderstorms are the result. But, these tend to be cells more than storm systems hundreds of miles wide. So, fly earlier in the day before the CBs build. The appeal of Florida is more probability of suitable VMC conditions, but surely less diversity of conditions that teach you about flying. As Gordy mentioned, you could get far more exposure to different terrain and climates that might be much better for experience if you were in places other than Florida.
