New Bike! Forced to use 170mm cranks (Im 6”6 or 198 cm)

Because of a terrible crash I broke my old Specialized Venge rim brake frame and my femur at the same time, so that bike is unfortunately gone.

I replaced it with a beautiful 2020 S-Works Venge Disc (61 cm), although I still cannot ride it yet while recovering from the broken femur.

The bike came with stunning S-Works carbon cranks (170 mm) with dual-sided power. I have always ridden 175 mm cranks because I am quite tall, so this is new territory for me.

My question for other tall riders:

has anyone around my height switched from 175 mm to 170 mm and stuck with it? How did it affect your power, cadence and comfort?

I know the trend in bike fitting is moving toward shorter cranks, even for taller riders, so I am curious about real world experiences before I consider swapping them.
