difference between 5lb traction&hanging?

I was wondering if there was a difference between hanging 5 pounds with weights or stretching yourself with a traction device to the equivalent of 5 lbs? (with penimaster etc) example: if you wore a 1-2 lb weight all day as an ads (like circle device or padlock) or you wore a penimaster all day with 2 pounds of tension. I don’t really see a difference as the ligs see a 2 pounds load. any ideas on this? My reason for this is I really have a hard time getting any thing to hang off my penis even with tons of wrapping practice and tutorials but I have no problems with the traction devices, not even most of the drawbacks other have with noose type stretchers.
