Right, it is not needed, it's just something I noticed after I had cut the RL for other reasons. But while hanging with more slack than a normally pitched ( "moderately tight" I think HH says) hammock will work fine for checking this theory out, it might cause some minor problems if it is decided that a good bit more slack ois more comfortable. Mainly because if the RL is very slack, the net might be too slack and hang in my face. Plus the RL itself won't be a nice tight line for hanging things on.
I look forward to reading the results of your test. For me this is just a suspicion I have that the calf area is more comfortable since I made the RL mod. I can't exactly do an direct A-B comparison of pre-mod vs post-mod.
For I consider that the sufferings of this present time are not worthy to be compared with the glory that is to be revealed to us....that the creation itself also will be set free from its slavery to corruption into the freedom of the glory of the children of God. For we know that the whole creation groans and suffers the pains of childbirth together until now.
