I would say from my experience and experience of others that carrying a lot of fuel for the fire (more than you think you need) is more important than carrying a lot of firestarters.

Carrying different firestarters and backups is smart, no doubt about that. But if I were to choose (for example because of the weight/space limit) between these two options:
3 firestarters plus small amount of fuel vs. 1 reliable firestarter plus lots of fuel I would pick the second one.
In reality this won't probably happen since I carry backups but I try to keep the firestarters somewhat small and make room for more fuel (tinder, kindling) instead.

When I got StrikeForce I thought how great it was - massive rod, big sparks, good for working with gloves on etc. but soon I realized that a middle sized version of "Swedish firesteel" type firestarter would still get the job done, would save a lot of weight and room that could be used for more fuel.

Of course I might change my opinion on this in the future and change my firestarters size/weight:fuel size/weight ratio based on another experience but now I think that more fuel is the better option.
It also depends on the weather, season of the year etc.

I am assuming your EDC, PSK, and camping gear all include fire starting stuff, which means on a camping trip you are always carrying a "kit" with multiple options if you are ETS.

I would have, for example: an EDC lighter and key-chain striker-ferro rod; a PSK spark-and-tinder quick plus a few REI matches and strike strip; and in the camping gear more REI matches and strike strips in a match safe, another lighter, a knife-ferro-rod-magnesium bar, and a piezeo-electric propane stove.

Of course we all know when you assume, you can make an "ass" of "u" and "me."

I agree with having sufficient fire tinder. I live in the PNW with an abundance of wood and rain. During the wet and cold season I always carry wet fire, cotton balls with vaseline and some fat wood. And I do carry at least 3 different ways to ignite a fire which includes a one handed method if injured. All that plus Doug's kit as another option.

One other thing to consider is always having a sturdy knife with you to shave some wood up to get the fire going. I also have some aluminum foil in my fire kit to make a little holder for the tender to shove up under the dry wood.

Probably the most important thing in getting a fire going in wet conditions is gathering and preparing the wood beforehand. Igniting the tinder is the easy part--getting a hot fire going can take some nursing it along.

I generally use a lighter 95% of the time (unless I'm deliberately practicing with a fire steel). Just so convenient.

I've got a Spark-lite in my PSK as a back up.

But I still carry matches. There are times when a lighter has a hard time, for example when lighting a lantern. Sometimes it's nice to be able to have a long thing match that can go through holes and such. Also, when building a wood fire, sometimes it's nice to be able to angle that match up under things in a way that I couldn't with a butane lighter. YMMV.

I ran across a dandy refillable butane lighter with a retractable tube that nicely solves this problem. It is about the size of a standard Bic lighter when retracted. I believe, though, that if I had to light a traditional Coleman mantle lantern, I would still need a match or a long splinter. I still have a Coleman lantern, but it is semi-retired (like me); mostly I will be using LED lanterns in the next power failure.

Actually I am still nostalgic about carbide lanterns. They provided heat and light and were an absolutely guaranteed fire starter.

One thing I do is hand out fire kits to those I'm hiking with: Ziploc with lighter, matches in case, tinder. They carry my spares. Also a tiny bic in the ol' first aid kit..

I noticed someone mentioning TP as tinder... I recently heard a trick about using the little TP packet from MREs as tinder. I haven't tried yet, but it sounds like a decent idea.
