thinking bout ordering my bday present to myself

what's the difference between the sv and t2? i see it has the sh motor , and by the pics, has more alum parts on it, plus the 2sp trans. anything else? is there a volcano that can be ordered with everything already hopped up? maybe a pro version of the volcano, be cheaper than adding all the parts 1 would think. be nice to buy a better version of the volcano.
