Looks decent to me. I've run test prop/tren ace/mast ace together, but never the longer esters. You said you've never run those two together, so I take that to mean you've used tren before and have an idea of how bad you get the sides.
From my experience (and from a lot of reading on here), a high tren/low test seems to be the ticket for preventing tren sides. I was using a blend when I used them so I initially was taking all three in equal doses - this gave me decent sides but not too bad. The last time I ran it, I got a hold of some more tren ace and mast ace, and raised the doses on those two while leaving the test lower. I forget my actual doses, but the weekly average was quite a jump between the two, and my sides all but disappeared. If you have run tren/test at the level you have it figured (only 100mg higher per week) and are good with that, then cool...go for it. Just food for thought.
As far as mast and tren interacting, I really didn't notice much there. My bodyfat was higher than it should have been (mid-teens), so I really didn't notice the 'hardening' that is usually mentioned from guys who were leaner to start with. I noticed my hair shedding seemed to increase, but I've also seen that since then with just test e and with primo. If you are asking about side effects/interactions between the two, I've never heard of any.
