So I'm getting from this and the longer responses, that you just go to it and see what works best for you.
BTW, mods, I didn't mean to split this into a new thread. :redface: I most humbly apologise.
To everyone, thanks for the responses.
I have a Pedersoli, still as green as grass, and Pedersoli is the only flint I've fired. Loved it and had to have one.
For myself, as a total know nothing on flints and MLs in general, I'm betting it was the expereince and not the rifle alone that turned my crank.
But I have it now and will be using it. The shop sold me FFF and FFFF, both in goex, to get me going. But I gather that FFF may be all I need.
Still, as soon as it warms up, I'll be out there making smoke and learning the skill.
