At 6’5 myself with an inseam measured at 37”, the “tall” bibs wound up being slightly too long in the leg area, but the strap length (and everything else) is perfect. May consider ordering the long strap / regular inseam version whenever I order the next set.
Despite the minor length issue with the inseam, I’ve been able to just about double my mileage vs. the more expensive Castelli bibs I was wearing before.
