In reply to jezb1:
You rack them closed. If you clip the axle it isn't too bad, but letting them dangle is bloody awful.
The two big problems with them imho are:
1. The sides do not move independently in the same manner as cam lobes, so they are useless in flared cracks.
2. you need to open them with both hands, which effectively means at the bottom of the pitch where you mean to place them.
The good points:
1. Cheap.
2. Lighter than most huge came.
3. WTF/trolling points.
