Okay so this is kind of a two part question...is there a formula for finding out at what points the splices need to be made for various fixed loop lengths? I.E. for a 5 in loop mark the splice points at such and such in. marks, for a 6 in loop mark at such and such in. marks. My reasoning for asking this is because I am thinking I want a bigger fixed loop as I am not whipping my hammock in the traditional manner and then attaching the sling with a larks head knot. Instead I am utilizing what rayd888 from YouTube refers to as the hammock 2.0(for those of you not familiar with that here's the link... http://m.youtube.com/watch?v=AJlEQpcbM1I ). Now in the video it shows the knot being tied with a continuous loop made by a double fisherman knot which is why I was thinking a bigger loop is needed. The second part of my question I guess would be do I need a bigger fixed loop to attach the whoopie sling in that manner, or would a regular size fixed loop work just fine? Sorry if all that was a bit confusing, hopefully I made my point clearly enough. Thanks ahead of time for the help!
