I don't think you need to cut macros to slow weight gain, as it will naturally peter out on its own- then again you might be right.
I like high carb days on days preceding heavy days (Day 1 and 3 of the typical TM setup) if you have to train in the AM. I'd aim for a 400-600kcal bump and have carbs high with fat lower....something like: 200/450/55
