I have smoked plenty of Arganese and I can tell you that I have had little problem with them holding their ash! Most will hold an ash more than halfway through a cigar.
I haven't smoked one with mixed fillers either. All have been long filler.
I'm curious about the vitola. The PCs don't hold ash as well as the big guys. If it was a bigger cigar... I would go with storage as the issue.
Construction isn't the issue with Arganese... I'll leave it there!
As far as ash goes... Long ash proves nothing about quality.
