Um, those are opposites.

A big stack above the top cup means they want more height, and they sure don't want to trim the steerer tube.

With spacers, and the stem flipped "down," the look approximates a quill in some ways, and avoids what some consider an awkward look with the stem flipped "up."

Trimming the steerer tube is basically same principle, in reverse. They lower the steerer end to get the height they want. If the stem is flipped "down," this is often called "slammed." Some prefer that fit, some prefer that look. With the stem flipped "up," and the steerer trimmed down, the fit may be right, but many feel the look is awkward.

If it's all about fit, there is no wrong or right way. I have a friend who has spacers above and below the stem; he has no issues with the look at all.

If it's all about the look, there is no wrong or right way, despite what you may read on the Road forum.

There are many times when the low down "slammed" fit just does not work. Back problems, neck problems, fitness levels, body structure, etc, all combine to create a fit that a person needs, not always what some other person wants.

Fit your stem the way you want, tell the naysayers to go ride a bike.
