Ok guys, these showed up today...
It will be a little while before I can fully test them but I had to quick fire off a couple to see how they compare. The quick take away is, these things are a lot faster than the eBay ones, both in ignition and burn time. Here's a capture using the same 5 ohm resistor setup that I've been using. I trimmed the 1m Firewires to the same 30cm lead length of the other ones to keep things on equal footing.
For the first one, the element conducted current for 1.62ms before fusing open. The second one (trace above) conducted for 1.57ms, so in general the element is lasting about 1/10 the time of the eBay initiators. You'll also notice that right after the element opens up, the plasma current starts to ramp up right away, only lasts a little over 2ms, and ends rather abruptly. This also coincides with what I observed. The Firewires have a loud quick pop, almost like a small firecracker going off whereas the eBay initiators have a small pop and then burn for about a second.
