Fair enough. The conclusions we have are based on our experience. If I watch the ZJH vs Morten Frost match together with Tang Xinfu, surely our conclusions would be very different. I was a competitive player, represented my club and was for some time was selected to represent the territory where I lived. Trained under professional coaches - Chinese national level for years in a sponsored club. I did some local tournaments in singles and doubles. I played some other XD matches partnering with a lady who used to be a Chinese team player. A fast paced game is not everything. Can go back and watch for example Dong Jiong vs Hoyer Larssen. Actually I don't have any problem with your conclusions. All of us have different criteria when judging the best players. For me the all time best is Tang Xinfu, and of course this is for me only. Yours might be somebody else.
