These are the prototypes for the TB110 72A that I’ve been testing.
The things I’ve noticed: they feel as soft as the 74A, not really any noticeably softer in my opinion. They seem to do better on wet surfaces than 74A. They do better on small pebbles and loose debris than 74A. Longevity makes me nervous; I am worried about lifespan. But since I’ve had these in my possession, I have put as many miles (kilometers) on them as possible, and been as hard on them as possible. Trying everything to make them fail on 3 different skates, one longboard and two shortboards. For anyone wondering, here they are right now:
No chunking at this point in time.
