It has been suggested to me that I move my adsense block up on my blog so it is above the fold.

Before I do that, I have a question:

Which would be more effective:

1. Using the big skyscraper block like I have and just moving it up on the page so it is above the fold

or

2. Using a smaller horizontal block that automatically gets inserted right after my signature in each blog post.

What do you all think?
