Wheel Durometer

I have a very particular situation. I have an in-line tournament coming up in a few weeks and the last set of wheels I put on my skates were 80A when skating on asphalt.

The place where the tournament is being played is normally an ice rink. It has what I would call semi smooth concrete. Except for about 6 inches in from the boards where the concrete has been absolutely chewed up.

I am 280 pounds so I’m not light. I’m thinking maybe an 82A or 84A might work best. I would love to hear opinions.
