Ditto, unless there are other factors than trail affecting handling. I've had a 56cm 700c LHT, presently have a 26" wheel LHT and a 56cm CrossCheck. According to the trail calculator they all have nearly the same trail but the 700c LHT is out in left field wrt wheel flop and lack of responsiveness at low speeds compared to the other two.
