the grand tour kodi add on works well to and is in 1080 as for putting kodi on firesticks/android boxes it easy ive just started doing re loads etc for people there are some great guides on youtube search for kodi solutions his guides are easy to understand and usually what he recomends does work well as the firestick is only around 1gb you need a lite build that way they run quite fast then.
