I'm in the process of switching to the Infexion QR system for my bars. Well actually, currently the only bar in service is my Flysurfer clamcleat bar for which I've fitted a new and longer trim line, to compensate for the length loss of the old QR.
I have a bunch of old 5-line bars that I've stripped down, and would like to make three bars for different purposes that ideally can stay connected to the kites.
First effort is a 45cm carbon F-one stick with 15m lines for 16kts+ foiling. Started to build this one in sleek-as-possible 4-line configuration with flag out.
Critique me on the following please:
The top section that connects the flagout line/powerlines and trim line is made out of 5mm dyneema and two 5x7 lightweight rings. It's a short section of 15cm with two lock splices, of which I buried the two tails together instead of the regular way. Then I did a whipping on both ends since I figured the buries are quite short and don't want them to slip. This was the nicest way I could think of to do it, but maybe there's a better idea out there? I suppose you can't bury two tails together in one piece of string, that would make it more pretty as it would have a single line center section. What about strenght? Good enough?
I was planning on running the flagout line through it, with a little plastic ring that I scavenged from the old bars that stops the larksheads from the flagout line going through it, thus transferring the power. The other powerline can just have a larkshead just below that ring.

I am very happy with a pure rope-based flagout system following the idea that was posted by Evan (Mr Infexion): you take a piece of 2-2.5mm dyneema and splice a small loop in each end. But the two loops are interlocked to form a small hole for your flagout line. No mechanical wear and seems to work great. OK, pretty useless without a picture....maybe someone can find the post ...
The rings used are actually really light, way lighter than the stainless blocks I found on the bars I had anyways. But the rope-based idea sounds really good, but it does probably need a stopper of some kind on the larkshead or not?
The thing you have to remember about 5mm dyneema is that it's vastly over strength for our application. It holds about 2 and a half tons. The reason it is so thick is for durability. This means that you can knot it where ever you like and it will be fine. This is unlike kite line where if you knot it the line will snap since it's not over strength like that 5mm lines. If you go with the 2 slider idea I would probably knot the dyneema as it will make that double loop line much shorter than a splice. A splice requires a certain distance for the bury so it will need to be longer than a knotted loop. I sometimes use 3mm line instead of 5mm for that section of the bar then I do splice it but 5mm I always knot it unless it needs to feed through something that requires a splice. I think your short bury Brummel will be fine. Typically we don't use a short bury because it is so much weaker than a long bury but here it's fine.
