I'm in the same boat as you though I'm leaning towards radiation. Still waiting on my Prostox test and the results of a little experiment. The experiment is taking Aleve for 2 weeks and having a PSA test at the end to see if it goes under 10 from my last result of 12.8. The Aleve experiment is to see how much of my PSA is from inflammation vs cancer. If it drops below 10 I'll be low intermediate vs high intermediate and I'll be able to skip ADT. The Prostox test will tell me if I can expect serious side effects from RT; if so, then maybe I'll consider surgery.
The options are overwhelming. I know how you feel.
Good luck to you!
