Looking over cuyugad's list if you choose to use T7, I might suggest the use of T7-fffg (3f). It is easier to ignite and it is so fine it will migrate out under the nipple with a little tapping. I have used it in both of my 54's and in the cold dead winter it has functioned my reliably than 2f.
If you choose Black Mag 3 it is already 3f, but it is hard to find in some places.
Good luck...
