Well, you are facing some important decisions. I know that the guys will be chiming in with their opinions. I am female and have not had an RC, but have been moderating here for a long time, so can send on some second hand information!
As you probably know, this is MAJOR surgery, and there is quite a long recovery and training time. At your age, and in your physical condition, my gut feeling is that you should seriously consider the neo. The most important thing is that you have a surgeon who is VERY EXPERIENCED in this procedure....meaning someone who does several of these a week, not several a year. This is critical to your success.
Sometimes, when the surgeon is actually into the operation, it becomes apparent that the pre-selected option will not work, and the default is the ileal condiut.
There are many men who have been on the Forum who have a neobladder and do such things as scuba diving and driving race cars! They report that a really "tough" attitude helps!
Good luck to you
