Which one would you choose?

I have raced st-r last year and st-rr this year and love it, only broke a few parts but it was my fault I would go with the st-rr parts are easier to get at hobby shops plus it already has big bores if you bought the xt8 you would spend another $100 on upgrading the shocks I have raced the jammin, kyosho, mugen and losi and so far the kyosho has been the best for me I just bought a rc8t(another option) and I am REALLY starting to like it
