I have a BL Sas too. Went with 1.25"Boras and thought it was too much poke so I switched them our for 0.75" which I like. It's just a personal thing but I think 2" would be hanging way out there.
From Florida I hope you're flying in to Vegas or Salt Lake and renting a car to drive to Moab. If she hasn't seen that part of the county it would be a shame to miss it. Lots of other stuff to do. A day or so in Vegas, Arches National Park and Castle Valley in Moab. You could do a one day...
