Everyone is going to be different. We all have a unique response to different drugs. The higher the dose of test, the more AI you need to use to control estrogen, which will otherwise blunt your attempt at fat loss. If you decide to take more test, I would watch your physique and see how you respond. If it's making you look softer and more blurry, you might want to add more AI or lower the test back down. I don't see anything wrong with what you are currently doing, as long as you feel ok. If you find that your sex drive takes a dive or that you are feeling overly lethargic and tired, you might want to use more test. 

There is a lot of talk about the middle easteron bodybuilders now days and how dry and crisp they come in. Many are suggesting it's due to them using far less test than the Americans. I've never cut my test out completely but I can say that it is much harder to look diced when you are running higher doses of it.
