Why is the TFT a "must have"? What does it do or what information does it provide that makes the previous unit completely obsolete? Or is your comment PURELY subjective?
Whichever model you get the TFT screen is a must have. The Michelin Anakee 3 tires mine came with are a lot sticker than I thought they would be but my replacement set are going to be Dunop Roadsmart 3 as I don't take it off road. While I don't have the rally model my GS came with the spoke wheels and I like the looks. I was able to get another K knocked off so the extra 2k went for the bags and GPS. The stock 2 piece seat mine came with sucks and a Sargent is on the way so my guess that you'll want to replace that single seat the Rally comes with as well. Make sure it comes with the Dynamic pro plug because once I inserted that thing it really came to life.
