I was reading thought an online review looking at some 2010 gear reviews and I saw a picture of the one pump system on the new blades, they have got a great clean idea to keep the tubes and clamps out of the way, preventing rubbing and pushing through the kite so simple and logical "after" you have seen it ;)
It's not a bad idea but others have dealt with the same problem by putting a neoprene cover on the clamp which solves that problem completely.
The remaining problem is that the elbow joint coming out of the bladder pushes up against the fabric when the kite is folded and eventually rubs a hole.
