Yes, I am clearly an outlier. However, using using stack and reach with some online calculators to mess with stem and spacer configurations nails it for me every time.
Using a "
fistfull of seatpost" is really no better than using stand-over to fit a bike.
Heck, in the MTB world, Reach is now the primary number used to size bikes.
