UT vs FL to me is mainly cost.
Ut is the cost of the course, 62.50 for 1st 5 years, 10 for 5 rear renewal after that
Fl is the cost of the course (could be FREE! Hunter Ed, military, or NRA (not free) course), 117 for the 1st 7 years and renewals are the same for 7 years.
As far as PA, I'd call them BEFORE sending it in the mail. There was a law change where they had to take your photo and digitize your signature on their equipment.
