I cannot really comment on this as I do not use inks that would be so thick that they could have potential flow problem... In fact I mostly use j herbin fountain pen inks even with my dip pens. Besides their characteristics I like the fact that they are easily removable from the nibs even when they get dry...

PS The e-shop I posted link to above sells j herbin ink too.
I have used everything from William Mitchell, Esterbrook, Bruase, and of course Speedball.
I use a combination of each.
I find that the Esterbrook Text Writers / Manuscript pens are some of the best (they are similar to the William Mitchell)
The Speed Ball, especially the vintage kind, are not too bad. The older the better. The Newer ones seem to scratch the paper and I have alot of difficulty with them.
However, the Esterbrook Drawlet Pens are something of a disaster.
