Nice to see I'm not the only GoGo user in these forums! What I did is a little complicated to explain, but very easy to do. It involved rearranging the order of the poles, and using some of the pole segments from the smaller half-arc. I ended with a perfect fit with 3.8oz of pole. This removes the weight and clutter of the airbeam, the foot pump, the spare bladder, and the bladder repair kit. Here goes:
The Lightsabre comes with two sets of poles: the full arc that goes from shoulder to shoulder and the half arc that goes behind your head. The full arc pole comes in 7 pieces; 4 curved segments (2 on each side), 2 straight segments (the lowest 2), and a small v-shaped segment in the center top. The half arc has 2 curved segments, 1 straight segment, and a V-shaped segment. Here's the trick: the V-shaped segment on the half-arc is less angled than the V-shaped segment on the full arc. If you use the V from the half arc, you get the proper curve for the GoGo.
Start by removing one of the metal end pieces (they easily pull out) and untie the bungee cord knot on both poles. This will separate all the parts. Then arrange the poles as follows:
Connect 3 of the curved poles, then add the less-angle V-shaped segment (from the original half arc). Then add another 3 curved poles. Insert the bungee through the arc. Unfortunately you will not be able to use the metal end piece, as it will be too large for the end of the curved piece (remember, the original full arc ended in a straight piece, which has a larger diameter at one end to accommodate the metal end piece). You will notice when you disassemble the half arc that the same problem occurs, and BD's solution was to tie off a small washer onto the cord, which fits into the pole. Use this washer to tie off the cord at the end of the last pole.
As for protecting the corners of the GoGo, I attach the caps from my hiking poles. I have two kinds, the small plastic caps that came with the poles (0.1oz pair) and a pair of Leki rubber walking tips (0.8oz pair, sold at REI). Though the Leki tips are heavier, I much prefer them, as they grip the silnylon floor and stay in place, and provide great protection from the pole ends. To keep them on the ends during assembly, I have wrapped some duct tape to make a larger diameter. And now I have some more emergency duct tape!
I have found that this setup stays in place so well that I do not need to worry about strips of Velcro to attach it to the GoGo Velcro tabs.
Here's where it gets even better: I discovered that two of the curved poles fit perfectly into the slots of my SMD Starlite backpack. They are the exact same length as the curved aluminum rods, and the exact same curvature. And because the V-shaped curve is so small, I am able to fit everything perfectly into my backpack (see photo below). I’m pretty sure this would work in a Mariposa as well. This shaved an additional 5 oz out of my total gear, making a total weight savings of 10oz! Pretty impressive for such a cheap accessory. Here are some pics:
This shows the custom pole and the remaining pieces. You can see that the non-used V-shaped segment is too angled. I've also included the aluminum stays from my Starlite to compare the curve.
This shows the curve of the poles from the back of my backpack.
Here's how I get the whole pole to fit into my backpack. You can see that the lower poles are inside of the Starlite's stay holders, and the upper parts of the pole drape down into my bag, out of the way. This wouldn't be possible without the smaller V-shaped segment. I imagine you could bundle this up into a foam pad and use it in a backpack without the aluminum stay holders, but this particular backpack hold everything together nicely.
Here's the pole in the GoGo. It's loosely setup with no stakes, but you can see the perftectly taut arc.
Finally, Here's the inside, showing the rubber hiking pole tips. I like how the pole fits into the long, narrow black sylnylon segment (where the airbeam normally goes). This keeps the pole away from any seams, which might cause leakage under such tension.
You can order the poles through BD's website for $25. Hope this helps! I'll be happy to answer any questions if none of this makes sense when you attempt it.
