taking my top off...one or two straps?

i thought of buying 2 of those bike lifts and call it good, but i would be right at the max weight
I have a 20 foot fiberglass extension ladder hanging from one right now. I'm not worried about the metal parts but the cord is really cheap and I keep waiting for it to come crashing down one night. That being said it has been you there for 10 years so I guess it is ok
