Advice on a 6th (final) pen/contrasting pens

[penwash]

I'll submit 2 ideas, both ebonite pens.

1. A big woodgrain flattop. A Wahl-Eversharp Decoband if you want to be fancy, or something like a Lincoln (National Pen Co.) if you want something that (in my eyes) just as beautiful but less hit on the wallet. If you get a good body, then you can take your time to find a nice and flexible vintage nib that will fit the size.

2. Eboya. They are made by the same company who made the Nikko ebonite. Just a few models to consider, and go for the big model. Beautiful pens that will contrast your current set of curated collection.

This is quite attractive to me...

Any ideas of how hard it'd be to find a correct flexible nib for it?

Wahl made a lot of nice flexible nibs, so you may luck out and get a flexible one on the Decoband already.
The hard part is to find a sample of the pen that is not exorbitantly expensive.

I would consider pen shows or high-end vendors like Pete Kirby (Petespenshop.com) or go-pens.com or ...
