Quite a lot same line lengths in bridle upper levels, so shape must have been taken care of in primary lines, but why not. Same lengths of course make it easier to check if there is some shrinkage happened in the bridle ("long mixer test").
In line plan C line row second level is marked as DC 60 line, IDK if that is correct but it is quite thin even though it is C line row. IMO it should have been DC 100 like in B line row. Also A lines have same line thicknesses on different levels. These designs mean 2:1 loads for same line strength/thickness.
Mixer is usual 1:2:4 and line row locations are quite even. So apparently there is not much if any camber change during powering up. But at least camber isn't decreasing when AoA increases
Bridle is spaced about 2-3 cells which is perhpas a bit conservative but for sure good choice. Inner structure seems to be H-ribs from A to C and lots of usual straps. Lots of weight reducing cuts in these parts. In TE there is "little ribs" which are usually known as mini ribs.
AR increases slightly for bigger sizes. This is done by "stretching" kite but because cell count is quite high 55 it is ok. Other way to do it is to design every size separately.
For sure this is an excellent kite for its kind but nowadays FS is not alone with this kind of products. For example PL Aero V2 offers very high performance and quite nice usability with a bit more higher specs than Sonic3.
