1) Surge is designed as a 4-Line direct-to-the-kite configuration. There is a 5th line anchor for those who want one. We are also investigating other alternatives for heavyweights likely to use the kite in more extreme conditions. The design trade-off is a 5th or other support lines or bigger LE tubes (and higher weight) meaning a slower, less eager to-the-edge kite. Our choice is to avoid oversized tubes as insurance against the kites being given a bad rap by those who choose to use them outside of a reasonable range of wind and rider weight. Larger tubes would accomplish this but the kite would fall below our expectations for performance by sitting back in the window and being sluggish in lighter conditions. This is really the only remaining decision on the Surge production and it pertains to the 9 & 11.
2) The wingtips are fairly wide and the front line position is balanced with the aerodynamic center so the bar pressure is medium-light and consistent through the range on a fixed or unhooked set-up. Felix's preference is to be able to feel the kite but not have to compensate his strapless stance or grow weary flying it. Clearly if you CL the Surge and sheet out until the rear lines go slack, the bar pressure falls to zero.
3) Surge has 'hard' composite battens only. Some early protos had inflatable tips. IMHO, there is no need to have both. We feel the hard batten is lighter, gives the kite a tighter, more responsive feel and being independent of inflation pressure, is more reliable.

1. Never got my question answered about whether there are any bridles on the Surge or not? I assume it is a direct pigtail connect to the kite? If so it must be the stability of the kite that is allowing for more depower than a conventional C when using a SLE type of bar. To tell you the truth I don't think we ever tried using a long throw / SLE type of bar setup on the older C kites, so I don't know what the outcome would have been. Certainly on some older C kites it would not have worked with a SLE long throw bar as they were prone to Hindenburging.
2. It was mentioned that bar pressure was an element of the design that was given effort to make it to Felix's specifications. What is the bar pressure like? Heavy, medium, light, and is there any ability (alternate pigtail locations) that the rider can customize the level of bar pressure? Is the bar pressure progressive with the amount of trim given the kite (light during depower and progressing to heavy when fully powered up), or is it more consistent through out the trim range?
3. I noticed in the picture of Felix holding the red and white Surge upside down, that kite seems to have an inflatable strut at the end of the wingtip, where the pictures of the green Surge looks to only have a hard batten at the wingtip. Was the inflatable wingtip strut a prototype, or does the final designed Surge have both an inflatable wingtip strut with a hard batten next to it?
