Help a prospective International Transfer Applicant: Retake SAT or Subject Tests?

<p>Hey CC!
I will apply to some top US-colleges for this enrollment cycle. Since the transfer deadlines are around March, I can take another SAT in January. But which one?
My Dec SAT scores: 760CR 800W and 630M (no idea what happened there :D ). Thanks to a previous SAT with a 720M, I superscore to 2280. Now, should I retake the SAT in January for sth in the 2300-2400 range (which hit on almost every practice test) or should I rather (re)take some Subject Tests?
The Subject Tests I have to date are unfortunately all 700-ish: Biology 740, Math II 710 and Physics 690. In January, I would retake Math II and Physics and take an additional Chemistry test. I think I could make 800 on all of them this time, since the percentage of stupid mistakes has dramatically decreased.
So, retake SAT or add/retake some Subject tests?</p>
