Welcome to the cub no man wants to join on his own, I assume you must live close to UF Gainesville if you are considering RALP there. I did a lot of research before my RALP and my first choice for treatment was proton beam therapy (PBT) and the closest facility for proton beam was UF Gainesville 300 miles from my home in AL and BCBS of AL would not pay for the PBT. IMO your small tumor and G6 makes you a perfect candidate for PBT If it were me take the time at UF to get a consult with the PBT guys, My URO's brother had it for his PC 5 years ago at Loma Linda Calif where PBT was first developed. His brother has no side effects and has been cancer free for the last 5 years.
Here is the link to UF's proton beam web siite:
Good luck my PC brother
