Haven't had the erdms but I heard from a buddy who is an erdm whore that they're good (you said it in pm also so I figured I can't go wrong). Plus these vitolas are going to be discontinued someday so if I like them going to stock up, I love the wrapper to filler ratio it's like flavor city.
Wasn't a big fan of the petit robusto, I really wanted to like it but it tastes exactly like a mini epicure especial! I have EEs and they're not as good as when I got them so I'm going to sit on them for awhile (they're 08s). I've been told psd5s are pretty fucking good so I'm keeping an eye out for when they get back in stock, price is stupid though.
