this will only benifit someone who is a gram counter of the most desprate kind. and i would like to appologize upfront if this has already been done as i'm a newb to the hammock world and hammock forums.
i'm awaiting the delivery of my whoopie slings today and i realized that i need some toggles cause i didn't purchase any.
i haven't tested this yet so bare with me.
for most of us that archery hunt, aluminum arrows are pretty much a thing of the past so i didn't have one to sacrafice in the name of the hang. what i do have is a ton of carbon arrows.
i cut one down to abut 5 inches and sanded the ends down, carefully drilled holes (carbon is bad about splintering since it's woven in fibers). i used the guts out of 550 cord to make the lanyard and finished it off with some high reflective tape used on aircraft and aircraft flightlines that i happen to have roll of. if i drop the black toggles at night all i have to do is get some light on the situation and they will shine!!
the total weight of the toggles, reflective tape, and cord was 4 grams.
i plan on testing it today, but in theory it should hold up better than the aluminum ones i would think. if alluminum gets a weak spot like a dent, it compromises the structural integrity of the cylinder. carbon tends to have more bend in it without failure.
with that being said, i can't imagine any situation within normal usage that you would run into any problems using aluminum arrow shafts as a toggle
here's a picture of the ones i made
