That is what I get when I pull the info after I've loaded the first chunk.

That sounds very much like what I do. I show the initial page, let the
user select the desired info and then I go to the appropriate route. I
display initial info in a header and footer, and then a js onLoad
function grabs the remaining data from another route (similar to your
results route). Sometimes that's a lot of JSON data and can take some
time do download. I use datatables for the actual load and display for
some of the routes.
