I would think that if the vibe was right at Colgate, Trinity is also a good fit in this regard. Trinity is quite strong in economics (even if it’s just a minor. ) Trinity also had s couple of special history/humanities offerings.
If he’s truly ambivalent, follow the money. I don’t feel like these two schools are of particularly different calibre. FWIW, while my kid ultimately chose a different school, Trinity stayed in the running for him until the end whereas Colgate did not.
