245 lbs of solid muscle is sick but you're fricken tall too so adding mass is key. You know what you need to do and what you need to work on so have at it and good luck. I certainly wish I had the time to put into developing a BB physique. I like one thing you said and that was that you didn't want to do too much T so as to not burn out too quickly, smart man bro, smart man.
**edit**
When you get a chance, I'd love to see your workout and gear regimen. Do you plan out your gear a year in advance or 6 mos. at a time or even smaller time icrements, depending on what you need to work on?
