I'm right about at the OPs power range myself. I also throw (mostly) Latitude. And similarly, I refuse to give up my Buzzz. I've tried and discarded a lot of Lat molds, but I also don't carry that much.
A lighter GL Flow could be used for anny shots. I recommend a Diamond or River for pure anhyzer shots, though. But learn to hyzer flip the Flow and you'll be pleased with it as a distance driver. The Saint, for all it's tredy hype, is truly one of Lat's most reliable and easy-to-use discs. No all-Lat bag should be without one.
The River is a strange bird. For the first year, I hated it. Once I got in tune with its sensitivity, I fell in love. It's one disc that's like my Buzzz; it will never leave my bag.
I personally love a stiffer, faster putter. So Lat works for me. If you're into slower, beaded, or floppy putters, you may want to look elsewhere. (Or try a Judge from DD) I still use a Discraft Zone in my OS putter slot.
joshuajames and redrum touched on it as well, but the Trident is a seriously useful mid/utility disc. It's a fairway driver in speed only. The disc handles like a faster mid, and is just as easily controlled for those tricky get-out-of-trouble shots.
If you really want a bombing anny driver, grab an Air Bolt. Otherwise, I'd stay away from their speed 13 line-up for now.
That's my experience, anyways. A lot of Latitude discs are touchy. They are the definition of risk/reward. Hit them right and you won't stop grinning. Have a bad round with them and you'll question why you ever were a Lat fan in the first place.
