That system makes all kinds of sense.

I'm pricing this out before I place an order and get stuff, and I have 3 more questions:

1) Just to confirm, these are the nylon tees you were talking about for connecting the frame together, and for connecting the frame to the hipbelt:

2) You still prefer the Skyshark P400 tubing for a frame for carrying 30-40 pounds?

3) Do you use the .240 ferrules that Kitemaster sells to plug the ends of the rods, or does the .25 OD fiberglass solid rods work if you finagle them a little?

Sorry to ask all these questions; this is so very cool, and I'd like to get as close to right the first time as I can.
