Maybe because at 34 my eyes are good enough that, to me, some clarity and brightness isn’t worth the extra coin.

Side by side by side shooting

SWFA 12x
SWFA 10x
SWFA ultralight 2.5-10
Leupold vx3i 3.5-10
Some brick of a Leica illuminated 2.5x10x50

Leica was bright and clear as hell, but I didn’t have a problem seeing what I was shooting with any of em.
