What would be a bigger advantage/disadvantage in a race in a convert. Top down or top up? Im guessing top up would be better but I don't KNOW that as fact. I dont know if a cloth top disturbs airflow more than helps. This is just a discussion, Im not planning on racing or anything and trying to find an advantage. Just seeing what the general opinion is, or if there is facts, even better. It's just a thought that has bounced around in my head.
