I'm the same as synthese oddly enough for all of those brands, and I am a 43.5-44 in GATs. Which really means I fit into anything between 43 and 44, but I wear my 43s laceless. 44 is a bit loose. If I got my hands on the white low 43.5 at forward, I could let you know about that.
I may be naive, but I don't think the majority of "regular" cigar smokers in their 20s smoke because they think it's sexy or fun. I'm 21 and I smoke because it's relaxing and something to do while I'm studying or lounging or something.
