@Pablo Looks like you are doing well with the plugs. If you like the Mick McQuaid I would advise you to stock up as I have seen comments on various pipe forums that it is being discontinued.
The only plugs I have tried are Revor and Warrior - both of which I thoroughly enjoyed but apparently Warrior is also being discontinued.
As for flakes I always have a good stock of Ennerdale and Grasmere jarred up. I have always found the OGS to be very good having first tried it in Denmark many, many years ago but I don’t smoke it as much as the Lakelands.
I completely agree with you about Glynn. I have his Breakfast Blend and Swamp Flower and will certainly be sampling more of his blends in the very near future. Also he has various GH plugs that are normally only available as flakes so you may want to check those out.
Enjoy your pipes and snuff.
