From the two options I chose bad, but that word is not entirely justified. The medium is not exactly bad but just almost never good enough. Not soft enough for the kind of track those work better and not that much faster than hard to justify the higher wear and the worse ability in running cool and thus taking push levels. It's more kind of sitting in between the chairs.

Useless tire, lasts less and is slower than hard.
Thank you for your participation.
Yes, I have found H to be the fastest overall and have a longer life and we can push more.
I think maybe M is currently useless for now.
