How to beat a dead horse...

66.68.123.158

For the sake of argument, lets say you weigh 175 pounds. You need to be airlifted out of a canyon after your car crashes down a ravine. Would you like the rescuers to pull you to safety using a rope rated at 125 pounds, 175 pounds, or 250 pounds max weight. Since you weigh 175 pounds I suspect you'd feel better if they used either the 175 or 250 pound rated rope. The 125 pound rated rope would probably work (maybe?) though for how long and with what consistency you would never know since it was not designed to operate at the higher stress level.

All three are round, look the same, are the same size, etc... and generally perform identical functions - ie. they are used to pull weight. All are in fact built to different specifications and are meant to serve different needs.

Think of the 6DJ8 as the 125 lb. rated rope, the 6922 as the 175 lb. rated rope, and the 7308 as the 250 lb. rated rope. It is perfectly safe to use the very strong rope to pull something light. It would be unwise to try the opposite. By doing so, you open yourself up to the risk of failure of said rope (or tube) since you are operating it outside of its designed limits.

Luckily, we are not dealing with life or death (except for the death of your tubes), you can do what you like and believe what you wish.

It sounds like you have confirmation that your equipment is okay with a tube of lower rating, as are probably most pieces of equipment using this family - it doesn't change the fact that these three tubes are in fact DIFFERENT!
