At the risk of getting too far off topic, it is possible to be guilty of plagiarizing oneself in a peer reviewed article. That being said, my original comment was ironically pointed at what appeared to be copying the Mako, since I'm well aware SVH was involved with DC on the MLX skate. The reason I thought it was worth noting was that if the heel had changed, maybe the boot had gotten lighter. It appears from subsequent comments that it has gotten lighter, although I'm not sure the heel has actually changed.
Back on topic, if the weight has come down, that's very interesting. My son is a Dman and since he's a bantam, shots are starting to hurt the foot in Makos. I told him he should get a beefier skate and Trues are better for that, but he hated the weight when he tried them on. So, if the weight has come down significantly, but they are still more resistant to shots than the Makos, it might be time to switch.
