Probably it is an optical system, couple of cameras and software with good calibration can estimate distances and heights very precisely.

The new one has 4 fins closer to the heel edge, while the old ones had them spaced evenly on the corners of the board, I think this also contributes to the upwind ability. If you are happy with the 4/5 maybe you just need to refresh them a bit - new straps and handle will be much cheaper and keep yo...

Bring the 17 and 10, 14-17 will have more or less the same wind range, if you have a big board(door) the 14 will be perfect for most days. The 10 for the off chance that there is a bit stronger wind (doesn't happen very often however it is possible). In general expect most days to have 8-12 knots, a...

It is heavier, but easier to carry as you don't have the middle fin trying to stab you in the ribs, it is pretty comfortable to ride that's all I can say at this point.

I was asking about the new flysurfer bar, however i don't th...

To learn to read?

The instructions that i posted in the second post are for all kites, so depending on your line length, and if you use a 4 or 5 line setup you can adjust it properly.
