HTS-2000.
Have you guys heard of this stuiff?
If you had the latest in alloy brazing rod technology available to repair that old 7005 aluminum bike frame, a brazing rod that is actually stronger that the original tig welding, would you use it? It's not Alumaweld, or any of the other commonly known rods. From what understand, it's relatively new. I couldn't help but scratch my head at the properties of this stuff.
Now, I'm no welding expert, so I thought I would post this here to see what the welders on here had to say or comment on this.

Here's the video they show.

I have an old aluminum frame I'd like to repair, and when I saw this online demo video, I couldn't help but ask a friend of mine who welds aluminum. He heard of it too, but never saw it use dbefore, as it hasn't been out for long. If this stuff is no B.S., then alloy repairs will become an everyday acceptance.
