First off, welcome to the forum ... especially as a contributor!!
The indoor and the outdoor Revs require different flying skills. You'll not get a huge boost to your indoor skills by hours of outdoor kite practice. Sorry!!!
Why don't you tell folks where in Florida you live ... there are at least three folks in Florida who frequent this forum. You might find someone who lives near you and would love nothing more than to help you become even more infected with the Rev bug. They'll have a much better idea of what flies well in that area of the state. Any one of the three will also give you and opportunity to try-before-you-buy.
Since you've already determined that you'll be flying Revs for awhile, and if you fail to connect with someone, why not save yourself a ton of worry and torture? Simply buy a full sail and a full vent B-series. That will cover 95% of the wind conditions that you'll encounter. The SUL is not a panacea for low winds ... practice and skill is the real secret there. The mid-vent is my favorite kite, but it gets flown less than 10% of the time ... darn winds are either too low or too high. The X-tra vent is a great addition, but it'll be used less than 5% of the time. That leaves only the full sail and the full vent as viable choices. If necessary, you can save a little money by buying the SLE full sail and full vent and still have a great time. However, buying the B-series with the additional frame sets will help you cover a broader wind range.
The B2 is a great kite, but not the best choice for a first kite. The 1.5 has the best balance between speed and precision for developing the muscle memory that's necessary for long time interest.
My opinion only ...
Cheers,
Tom
