Full RSS Site Feeds for better traffic

I have published my blog feeds through a number of publishers and a couple of them have now stipulated that full feeds, not partial feeds, are required. As an Adsense publisher I had thought a full feed would mean readers didn't need to visit the site so I would miss out on clicks. However the guys over at Feedburner, whose opinion I respect, advise there truncated feeds result in higher clickthroughs. Their advice is that good content rich feeds will cause your readers to subscribe and check out the comments. So I am sticking with full feeds.
