Sorry no piccies. Flew yesterday late evening: HQ Shadow and Polo custom UL.
Due to little 2-line kiting the last few years and especially during/since the last winter, the input through the lines was quite rough and unpolished. The line set I'd brought was a bit long (20m, 66ft) for the small beach and the conditions. I'd say it was a half session that didn't go very well in an absolute way, but was good as a training in gentle inputs and maintaining contact with the kite without affecting it inadvertently in the very light wind.
The quad piloting went better from the start. Even the catches went well. The polo, relative to the Rev B-series std, tend to glide longer and overshoot (so it can become difficult to catch) given the same inputs. With the Polo UL I needed to start with the kite a bit lower in the wind window than with the B-series when doing catches. The B-series that I have much more time on the lines with, tend to fall more vertically before the catch.
