I have built a Knotty method, and like it a lot, when there is unlimited space and weather is good. Construction is quite easy.
The only real difference in the two is that the footbox one I did, after the SRL is on it, is less than 8 feet long, and hangs in a smaller spot.
Your feet are almost right below the knot at the foot end with that type of footbox.
Lots of coverage with an 11 foot ridgeline tarp.
Knotty's keeps the gear inside just as well but the hammock overall is longer on the SRL.
The advantage of Knotty's is that there is no worry about the sides tearing at the footbox if you were to sit on that edge.
On mine I used a zing-it line, in the side hem to avoid a possible issue.
I have about 100 nights on the footbox one I built with no issues.
The wife has about 50 nights on hers. She is 5'4 and the hammock on the SRL is less than 7 feet.
The Knotty method one I have only about a dozen nights on.
When I do another I will do Knotty's stretch side on the shoulder side and the footbox on the other end.
I don't know if I helped, but all DIY is fun.
You might have to build more than one, just because you can.
