I doubt you're playing a double e (which is a third above a double c ed: )...probably an octave above last space E. But that's besides the point. If you're gonna play in college and after it would probably be a good idea to invest in a pro model instead of an intermediate. With the weight issue, that really should be a factor because I'd hope you wouldn't use the pro horn on the field. Remember, the pro models are made with 1 large piece of metal for the bell shaft unlike intermediate/beginner models that are multiple pieces. That means that the pro horn will easily dent and it'll be a pain in the but to get dents out. If you're going to pay $2000 (american I'm guessing), I would suggest looking into a used Callet model. They're mainly used for high jazz lead roles which usually get up to the double C range for pro players.

Do you take private lessons? If so, what does your teacher think? Again, go to a music store and take your moutpiece to try horns out! It's the best thing that you can do. When you play through the different horns, a good idea is to set a few models infront of you and close your eyes. Have a person take note to which one you are about to play. Pick one horn up and then play a phrase or melodic line with it (long tones are good too to check clarity). Tell your friend how much you liked it on a scale of 1-10. Then, once you're done, put it back into the "pile" (line on a table or whatever) and have someone mix them up. Then let them give you another trumpet and do the same melodic line on. Keep special attention to tone quality and clarity. Once you've went through them all, open your eyes and have your friend tell you which one you've graded the highest after a few run throughs. It may seem rediculous to do that process, but it will truely help your brain and ear pick the horn that's right for you.
