I enjoy demos lately aesthetically as the color can be what ever I want to write with. I considered several other pens for this purchase but the versatility of this pen won out this round for my needs. I agree though, it would be nice to see more variation. I would have loved the Antwerp but the cost variance didn't justify itself to me to have red.
Even I considered the red as my interest in orange ebonite was waning. But i prefer pilot nibs over generic bock or anything else and have a red pen from them (Namiki Urushi #50) so didn't feel like going for it. I don't take filling system into consideration anymore. I would appreciate it for a while before losing interest, and if the pen doesn't look nice, it will probably be sold in 6 months like the Monarch.
