I ordered a bunch of nibs for my Lamy Accent from the writing desk in the UK.
I ordered an EF, F OM and 1.1i. My Lamy came with a MK nib.
I think the F (I know, very plain

) will become my favorite nib for this pen. I don't like the OM at all, it's scratchy, has a narrow sweet spot and lays down a very dry line. The EF is just a bit too narrow for my taste, but otherwise works well. The 1.1i is a lot of fun. I puts down a very wet line (cool!) and produces some nice line variation. If I ever start to practice different styles of writing, I'm sure I will have a lot of fun with this nib.
The MK nib that came with my pen is also a nice nib, bit a bit too wide for my taste.
For just a few pounds each, those nibs are a steal. And a nice introduction to different nib-styles

I'll probably order the other 5 styles (I'll skip the LH nib) sometime in the future too.
BTW: This week, I started using black ink again. I think I found my ideal ink for my waterman pen! Simply waterman black

My waterman has a F nib, which combined with waterman black gives a real nice line. I've used it for writing the summaries for my statistics course. It works really well with all the squiggely lines etc. Quite a surprise.
