Seems like there's a lot of lefties around here.

I've used fountain pens as my primary writing tools for the past 5- 6 years.

I don't have a crab or hook - I hold my pen as would a right-handed person and push it across the paper.

I only have problems with especially wet nibs or thick ink.

I can use a fine or medium nib with no problems - I generally use Waterman ink, which seems to work well with all of my pens.
