I'm in as similair boat as you. Higher total test than most, E2 high per labs, but feel fantastic. Going on the same protocol for 2 years now and labs continue to support the protocol. I'm staying with the protocol until labs or my Dr. tells me something different.
The only thing that concerned me at first was my Hemocrit values and thus I was donating blood fairly often. However, there are new opinions on the whole Hemocrit value and some Dr's (including mine), believe that the blood is not actually turning thicker and there is no danger in the higher value, similar to those that live in higher altitude. I'm testing this theory as I haven't donated since October and my labs are in July, so I'm going to wait it out and see what the values come back as. In the meantime, I have had no real change to blood pressure or any other negative signs that thicker blood could contribute to.
I sum it up to say if you feel fantastic stay with the protocol as it takes so long to get dialed in and your body adjusted, unless labs or Dr. tells you otherwise (excluding E2). A high E2 lab result if you feel fantastic means nothing, in my opinion.
