I have the older, silver spreader bars on my BMBH. If I remember right they were rated to 220lbs or so. I'm pushing those limits and have noticed the following (bear with me as I try to explain). The slit where the hammock's outer rings fit in the spreader bar, right where the rings rest (at the very bottom of the "U" slit in the bar) the metal is bending inwards. Due to the tips being covered in...whatever that black stuff is, I cant see if the bars are cracking. I'm wondering if anyone else has noticed this. I realize I could order the new bars from the jacks which are rated higher but I would like to save the 30ish bucks if theses bars are ok.
