Very interesting.  My latest labs showed a sensitive E2 level of 68 (total test was 1131, TE ratio: 16.6), and I don't have any high E2 symptoms...no itchy/sore nipples, no water retention/bloating, nothing at all.  My PSA level was exactly the same as my pre-TRT level (1.1).  I haven't had any prostate issues since I started TRT.  I'm on the daily Cialis (5mg), as well. 
I had my follow up consult with Dr. Crisler today, and he said that he treats ME, not a number on a lab test.  Since I was absent any symptoms, he didn't think I needed Anastrozole, and that's fine with me.  I volunteered to try EOD test injections (vice every 3.5 days that I'm on now) to see if that will naturally bring down that E2 level, and he agreed that I could try that if I liked.  I'll retest basic labs in about 6 weeks to see where I stand.  I also want to see if I feel better on the EOD protocol.  Ah...I just love being a guinea pig!
