First off, I know that Polyester webbing is the Go-To for tree huggers, but I am wondering if anyone has any experience with Polypropylene, or any other types of webbing. I am trying to get a SUL hammock setup and ordered samples of every style and flavor of webbing from Strapworks http://www.strapworks.com/default.asp trying to find a sweet spot for weight vs. stretch vs. strength.
The 1" Polypropylene (0.21oz/ft) is less than half the weight of the 1" Polyester (0.48oz/ft) and still has a weight rating of 900lbs, which I am comfortable with, seeing as my Dynaglide Whoopies are only rated to 1000lbs.
On Strapworks it says that Polypropylene doesn't have great abrasion resistance. Does anyone have any experience with the longevity of Polypropylene tree huggers.
Aside from finding lighter materials, the other option to shed weight is, obviously, using less material. What do you all think of using 3/4", or even 5/8" polyester tree straps. Do you think that these would provide enough protection to the bark.
Finally, There is also "Seat Belt" Polyester webbing. This stuff is lighter than the standard polyester, but has very similar strength. Is there anyone that knows how well this holds up in the field? I would think it would be OK seeing as I have never seen a torn or tattered seat belt...and those things see a lot of daily use-and-abuse.
Any constructive input would be greatly appreciated.
