As a left handed fountain pen user myself, I know how difficult it can be to find a pen that doesn't smudge and writes nicely. Everyone who has seen Susan Wirth seems to go away from her table with a great pen. I am going to have to remember to see her early at my next pen show.
I am interested to know what kind of ink Anne-Marie told you was fast drying. Smudging has always been a problem of mine and I am always looking for fast drying ink. I don't know whether Chuck Swisher was there but he sells some ink that is specially made for left handed users. I have three bottles and they dry very quickly indeed. Probably my most often used inks, but I need more variety in my fast drying inks.
Congrats again on your first pen show and a very successful one at that. Fountain pens are harder for lefties but they are well worth the extra effort.
I hope that you enjoy your pens for many years to come. -Jesse
