I have a pair of Ice Invaders and a pair of Lowe Lightfangs. I would
definitely NOT recommend the Invaders. The concept seemed great, and
since I was able to get a good deal in Chamonix, I bought a pair. I
liked the idea of a single pair of crampons which could be modified to
be rigid orflexible and had interchangeable front points. I have both
the vertical and horizontal (T-shaped) front points. Both sets of
front points have problems.
The vertical ones are too long. On steep ice, I can only set the
vertical points, and get no support from the second set of points.
This place too much torque on the front points, and heavy strain on
your calfs. Without kicking the ***out of the ice, its difficult to
get secure foot placements. Consequently, I always use my lightfangs
for waterfall ice.
The horizontal points are good for general mountaineering, and great
on neve. The extra width is more secure in softer conditions.
However, a friend borrwed them for an ascent of Pinnacle Gully on
Huntington's Ravine on Mt. Washington, and during a nighttime descent
of the Lions head trail (which was rocky and icy). When we got down,
the points were bent at the top of the weld, and had to be replaced.
Thus, I wouldn't trust these points for mixed climbing; they're just not
The lightfangs are great for waterfall ice, but are too heavy for general
mountaineering, and tend to ball up with snow...
The Charlet Moser crampons seem to be well regarded.
