Being in a similar situation, I would recommend creating annual blog posts and using canonical tagging. Then, in the previous year's version, putting a link at the top to the current year.
For example:
Top 5 Crickets in 2016
Thank you so much for visiting our 2016 page. For a more up to date version see our [link] Top 5 Crickets in 2017 page.
This way you get the best of both worlds without having to put in a redirect.
I'm not entirely sure what you mean by "then take that away." Are you referring to deactivating the mobile site?
I'd recommend going fully responsive and making sure you have tailored the responsiveness to work on everything from desktop to smaller phones (think iPhone 4). I don't see much of an advantage from launching mobile if responsiveness is already up to snuff as it were.
I have included the URL to a tool called "Ad Preview" by Google. It allows you to preview the SERP and put in these input parameters - Location, Language and Device. If you want to simulate different areas, you just put in a different location. Putting in the location "United States" should give you the most reliable data for your queries. You will be able to see the snack-pack in the SERP and it will be simulated for the location you gave.
