Turn fin size for 29" mono?

[flyboy320]

Looking at a 29" mono, like the Delta Force hulls, and am trying to figure out what size turn fins I need for sport running only. I have come across a few choices.

SV27 replacement ones;

Another one that OSE sells;

And an ebay one (this guy also has a slightly smaller one available);
