We ran into a group of guys last year on the larger northern loop we did, I do not recall which stop it was we met up with them at, but they came from and did a more southern loop as well like your run, but do not think it included over to Mt Valin and the St Lawrence, I know they said the southern portion was pretty bad - but last year was a bad year as we all know, even in QC.....this year will be great though!
