My response was a direct response to someone specifically mentioning the height difference aspect. If you have a scientific study to show why Sui/Han despite lack of heigh difference can still manage explosive pair elements that other Chinese teams like Pang/Tong, Shen/Zhao, and Zhang/Zhang and essentially every Chinese pairs team has despite all of them having different body types and differences between partners, then please provide it.
Nope, I don't have all that information. Maybe it should be researched and closely studied and a thesis should be written.

Maybe there's information out there that has already been written about body structure differences and athletic prowess that allows some athletes to generate explosive power and others to gain superior speed and others to master difficult, gorgeous overhead lifts, and others to execute superior spins with mesmerizing spin positions.
Perhaps there's a technique-related key that's missing for C/L that might enable them to gain more snap and explosive power on their jumps. I don't know. Probably Hao Bin has an idea he's not sharing.

C/L do train with Nina Mozer on occasion, so maybe she has the answer. It is an interesting topic, and my inquiring mind is curious.
Anyway, I do know that visually, C/L are quite pleasing to watch with their long lines and their engaging performance abilities. Sui/Han have dynamic precision, speed and power, and enviable presence and charisma that they have developed in recent years, but their overhead lifts are not as aesthetically pleasing as some other pairs (Alexa/Chris; Denney/Frazier; Tarosova/Morosov; James/Cipres) because Han's arms are not that long. That doesn't mean they can't perform technically proficient and difficult lifts that cover the ice. Their lifts just look different due to their smaller sizes and their lack of height difference.
C/L need to improve their steadiness on their lifts, and who knows perhaps they are working on the power conundrum with their throws. I'm happy for them that they are coming along very nicely for a third year team, and they've accomplished a lot. They appear to have grit and staying power. I'm not sure whether it's necessarily a productive enterprise to one-on-one compare teams with different physicalities, backgrounds, training strategies, and number of years working together as partners.
