Welcome to our club of guys who are so very special. This is a club you don't want to join, but when you do, you have lots of support!!!!
Sounds like you have done your homework. Knowledge is the best line of defense. When you make an informed decision, you never have to worry about "maybe I should have done....."
Best of wishes to you. You'll have our prayers. I was glad it wasn't nearly as bad as I had imagined. DaVinci was great.
Keep in touch..
