Disclaimer: The subject matter you're about to read is taken from my own systems and observations. I am not trying to condemn or advocate one system over another. I was just simply curious as to what I was really saving in weight between the two different systems I have. I am not going to discuss preferences, likes, dislike, fiddle factors or any of the like, I am just simply giving you what I came up within my "research"
I did not have commercially available whoopie slings so I am going off the weight of my DIY ones. They are 6ft when fully extended (Hence I call them 6ft whoopie slings) and took about 14ft of 7/64 amsteal grey to make, each.
I just use the loops that the suspension comes with, to affix them to the trees, but I will put in the weight of Dutch Clips in the end for comparison purposes.
My scale is accurate to +/-.02 grams
A (set) means two...which is what one needs to suspend their hammock from the trees.
Test 1: Stock Warbonnet Suspension
WB 12ft Tree Straps 5 1/4oz....148grams (set)
WB Triangle ring things (amsteal loops still attached) 1oz....30grams (set)
WB total weight of items:
6 1/4oz....178 grams
***This is what it would take to hang your hammock and what Brandon provides when you buy a hammock from him ***
Test 2: DIY Whoopie/Strap Suspension
6ft Tree Straps 3 3/8oz....94grams (set) (I just took some spare WB straps and cut them down)
DIY 6ft Whoopies 1 1/2 oz....44grams (set)
Dutch Buckles (in place of marlin spikes/toggles) 5/8oz...16grams (set)
DIY Total weight of items
Difference between the two systems: 1 5/8oz....48grams
Dutch Clip weight would add an extra: 7/8oz....26grams (set) to each system if you wanted to use them in place of above said suspension system.
***Side note***My tree straps I got with a new hammock I just received in the mail (review coming soon) comes with 6ft6in poly straps and they weigh 3 1/8oz....88grams....The hammock came with 6ft whoopies as well, but they are attached to the hammock itself. ****
So there ya go, that's the results/facts from my laboratory. And I hope you get the point I am trying to make....by not making a point one way or the other. YMMV
