Link Trading Q

[JoeBlack]

I was wondering if the index is the defining page for passing pr and/or relevance? Say I have a trade with someone other than on there index page...am I losing out if that page has a high pr in itself?

Example: If I have an asian site that is of all asian niche. If I link trade from my index to a general link list asian category which has its own high PR and traffic of its own am I losing out by allowing them to link back to me from that category page or would I do better getting index trades with that site instead as far as relevance and ranking goes?
