When I first started with SG flakes I had a pretty hard time with them, but I wasn't yet very experienced with flake tobacco in general. I got frustrated and jarred the FVF and Choc Fl and forgot about them for a year or so. When I tried the Choc Flake again after a long nap I had one of those sublime nearly supernatural pipe experiences that we pipe smokers occasionally get. One of the best bowls I have ever smoked, it was 45 min of pure bliss. That about 40gr or so of jarred SG choc FL provided some of the best smoke I ever tasted. Once I saw that potential that Gawith packs into those tins, I finally 'got it' and now joined the throngs of rabid pipe smokers smashing keyboards at every Gawith drop that makes it over to these shores...
But anyway, I can only suggest if you are having trouble with Gawith flakes, try rubbing them out *really* well into a ribbon. That worked initially for me to get me going. But I don't bother with that anymore, now I lazily grab a likely looking sized flake and just fold and stuff into my pipe and just light it. For this incredibly lazy way to smoke flakes to work, I can't emphasize enough that the secret is to pack it waaay looser than you would pack a typical ribbon cut. With practice you'll get the hang of it. Oh and don't tamp too hard either.
And yes the Gawith flakes can take a bit extra flame to get going. I typically use a Bic I would hate to try with matches. But once they get going, might take an extra try or three, I find they burn down to the bottom with minimal relights.
