Slimeline sell well in all the forms such as normal, fattop and longwood and in all normal finishes. Streamline sell well too and nowadays I'm selling more and more fountain pens of all sorts and think that the Omega is going to be a hit. You have to sell them though. I always carry a full fountain pen and if there is the slightest interest I get them to have a go on one and then consider it sold.
In some shows (not that I do that many) the Sierras do well.
What the best answer really is, is to stock as big a variety as possible because even though you or someone else might not like it, it will the the only one liked by somebody else.
