Sure, there are differences, but I'm wondering how much of an impact they have on the overall skate. So the TF7 is a little bit: heavier and not quite as stiff. Is Clarino a significant upgrade from the nylon wicking? Maybe. Is the low profile tongue "better"? Steel is somewhat of a consumable, so not sure coated vs. regular makes a huge difference either.
Maybe I am way off base, but I have a feeling the TF7 will be the popular choice for the value to performance ratio it provides.
