I took a new liking to saltpeter impregnated cotton - works like char cloth is supposed to work, without the hassle of charring (my first try at that didn't work). And then you need dry grass or leaves - anything you can form into a nest and blow it into a flame.
I also like the tissue trick (wrap that around a striker), though I'm not sure it would work with the GoingGear striker.
In natural tinders I like dandelion seeds - they are a flash starter, I use them with grass and wood shavings - mix well, have enough dandelion seed in it, don't crush while mixing, one strike ... add kindling ...
Then I have a charcoal lighter made from wood and wax, that you can light with a firesteel. They come packed in bars, and one bar is good for 6 or more fires in dry weather. I have one bar in my pack at all times.
