1 inch is generally the thickest..because they can congo by accident and end up 2 x 1 then 3 x 2 etc
yes when your at 3 inches that's like an arm...
we have a few members with 2 inch thick dreads but they take special care
we have 1 who has huuuuge dreads some like 1/3 of his head almost..but kinda shortish still (though haven't seen an update in awhile)
i can imagine they dry extremely slow and by now do pull painfully
