Traders' Roundtable

Does anyone know where you can find data on CTA's that let's you know what they trade? Specifically I'm trying to find a specialist in timber (if such a thing exists).

Most free CTA data will show you performance. I think for things like full TASS database access to find out detailed fund profiles, you need to subscribe to their services. There are others, but I cannot remember what they are at this moment.
