So I'm a large farm animal... I own two HH's an ultralight backpacker and a Survivor... So per the HH specs, I'm out of the weightclass for the ULB at 250#'s thought I've spent 20-30 nights in it and still have it in my bug out bag. Survivor is a great deal bigger and is supposed to hold up to 350#'s... I recently changed out my Survivors lines for a whoopie sling. Now the lines on my suvivor are a great deal beefier than on the ULB... Sorry, I'm getting to my question.

What dictates a weight limit for the hammocks usually? Is it the cordage on on the suspension? Would replacing my suspension lines and huggers on the ULB with the suspension from the survivor provide at least anecdotal increase in weight capacity?

Like I said, I've swung a bunch in the smaller HH but the last thing I want to do is have the suspension snap in the middle of the night with some wind. Thanks in advance.
