I have been wondering what is an overwhelming pipe tobacco in as far as strength. I for one have found Brown no. 4 by SG the strongest I have tasted, not overwhelming in my opinion, although I would rate it anywhere in between very strong and extremely strong. Tobaccoreviews.com rates it strong, strong being a 7/10 on their scale, overwhelming being 10/10, extremely strong being 9/10 and very strong 8/10. I have yet to find one tobacco on the renown site to be more than 8/10, and that is SG Black XX Twist. I am sure there are stronger tobaccos out there. Out of curiosity, not necessarily a bomb fan, but what is the strongest you have tried? How far up the scale is it as far as strength ?
