I would definitely check out the new Camp USA Skimo Tour Crampon or the Camp USA Skimo Nanotech Crampon. Both have a dual boot compatibility using either it's automatic front toe bail attachment or hybrid attachment using rubber toe strap. Semi-automatic toe bails sold separately for boots without toe welts for the Skimo Race, Tour or Nanotech crampons. Check out the C.A.M.P. Skimo Semi-Auto Toe Bails, Pair, 2589.
Another lightweight crampon that is good to have in your backpack when backcountry skiing, is the Camp USA XLC 390 Crampon. Camp USA says they are the lightest 12-point crampons in the world and perfect for ski mountaineering and glacier travel. The XLC 390 automatic crampon fit most rigid mountaineering, A/T, and telemark boots. Be sure to get the new version that has dynamic anti-balling plates, to help avoid from snow packing underneath the crampon. Keep in mind, if you're just using a crampon on occasion when backcountry skiing, then the Camp USA XLC 390 crampon may be the way to go. While the XLC 390 is sturdy, aluminum crampons are not suitable for ice climbing or intensive mixed terrain.
Alternatively, you may also consider the Grivel Air Tech crampon Cramp-O-Matic (made from light alloy) or the Grivel Haute Route Ski-Matic crampons (made from Carbon steel + light alloy).
If you are planning to also use the crampons to climb steeper / almost vertical ice, then you'll be better off to go with a heavier chromolly steel crampon, like the Grivel G12 Crampon with Cramp-o-matic binding.
