I'm a large chested guy and I must say...I hate the tri top. For me, I've got hips and it rolls up. Yes, I can eat better with it BUT it hurts like hell. I have it dig in my back and under my arms and it doesn't really compress better (IMO).
It does all depend on your body shape and chest shape...mine sag like whoa so when I bind with the tri-top my nips almost poke out of the bottom...it's weird. Might work if you're not as "droopy" or if your hips aren't so wide.
