Hey for everyone with the typical saggy bosal problem, I've figured out a cheap fix.
I've tried shorter rubber hangers and they look good for a bit until they strech and make their initial hanger tear in. They they look almost as bad as before, and 6 $ a hanger for 3-4 weeks of looking good isnt worth it..
Soooo...

120lb cable zip ties. they are 14" long perfect length.
So you can either use them in conjuction with an old rubber hanger and pretty much use a few of them as a hanger OR you can get a new rubber hanger and wrap these around it so it can't stretch it down.
These are extremely strong, none have broken yet in months of use. I have them pretty much taking the place of the rubber hanger pulling up the system higher than the rubber hanger could when it's as tight as possible. But I left the hanger there in case it ever dropped for extra protection.
