Nothing wrong with spacers above the stem,
for tall stacks, I'm liking the Cane Creek interlok spacers , they fit together like Legos.
Even better if you have their headset too, I don't.

I found restoring a cut too short steerer was a chore to make longer thru stem raisers and such .

I got one of QBP's locking spacers at the bottom, a little pinch bolt holds it there.

Integrated headset lets the fork fall out when stem was loosened, It wont now.
