The Pro Kit worked as advertised. By bringing the front lines back to the top of the depower strap, a more direct feel and a quicker responding kit to bar input was achieved.
Remember, this was developed for high end freestyle riders and was designed to be used with the Nomad. Your leash set up was to the depower loop. By pulling on the o-shit loop which was attached to the front lines, you would be accomplishing the same as pushing the QR and activating the IDS.
Although the Pro Kit worked with the SB, if I remember correctly, it didn't work as well as with the Nomad, as the wing tips would flare a bit.
Hope that's helpful...
It is helpful Steve.
In fact that's exactly why I asked the question.
The Nomad is a narrower kite so the V is not so wide in the front lines as with a Switchblade.
I'm copying the bridle on my Cloud 17m, but with the sliders allowed to slide more to the centre of the LE like on the IDS. On the German forum, they seem to reckon the Cloud 17 flies better with a low V and I could make the IDS operate through the bar and a swivel, thus keeping the low V but I wanted to know if the tension on the V of the front lines would resist and stop the bar going out to full depower.
I guess the only way is to try. Because the 17 Cloud has no struts, it has much less pull and tension on the front lines than my 13m Xbow has when flagged out on IDS, so I think it may work OK.
It all depends on how fast the tension reduces on the front lines as the kite is sheeted out, and how fast the sliders move to the centre of the kite.
