I just purchased a Lunt 1 1/4" solar wedge in the past month. In addition to a
wedge being the superior white-light filter, it has the added benefit of
tunable brightness. Without a polarizer, the sun is a bit uncomfortably bright
for visual use, but can be easily dimmed to a better level by rotating an
eyepiece with a polarizer in it. During annularity, I am anticipating that I
will have the polarizer rotated to a brighter setting, since the limb of the
sun is so much fainter than the center.
