Haven't But im in the market for something like this. I have a 997 or 977 whatever it is from underworks, It makes them a sagged b or c, no matter how much adjusting so I've been thinking about getting a smaller binder tank and the strapless brace kind to get super flat if possible. I hate my DDD chest/pecs. Maybe their binder works better for this guy, becuse the thought of two binders on in hot ass Texas or back home in Kentucky makes we want to cut them of myself.
