Would I do it again? Maybe… I would do a few things differently. 1) run a rope or wire around the groves in the kiln to get a better measurement on length, and 2) start installing from the middle of the element, rather than the end. I had planned on using one of the old elements for measurements, but they came out in pieces. I measured along the grooves and then multiplied, which gave me a close figure, but it was still about 4″ too short because of the way the elements twist around the kiln.
The biggest pain was the element I overstretched a bit. Ended up having to pin a lot which I’m sure could have been avoided by factory elements. Heated the kiln to about 750C then pinned and pinned again after the first bisque. I didn’t have to pin after the first glaze firing. I ordered the wire by gauge for my kiln, then turned the elements to the ohms listed by the manufacturer.
I did get it done, and the kiln now fires as it should. I saved about $150 by buying the Kanthal A1 wire but spent all day turning and installing, so it just depends on which is worth more, to you, money or time.
Wound but not stretched 
The purple strap is to keep it from rebounding on me if it happens to pull loose at the far end.
