I am after some info on the rotax dsc. Is there any difference between barrels that are a cast liner and nikasil other than the coating? And which one is preferred?

Do they both have the bridged exhaust port? Nikasil arguably transfers heat better and is a harder material. It’s more of a nuance than anything though.
But if one has an elliptical exhaust port, chances are that’s going to be a tad faster.
