I absolutely adore my twin Pilots... and there's that ink ... too much beauty! Actually, I didn't have the budget for a Metal Falcon and dialed my expectations down to get the resin version. I will point out that I both enjoy the metal body and added weight, as well as the larger cartridge.
It took me a few months to save for the resin body purchase. The night I went to order, I realized it wasn't what I really wanted and would suffer upgradeitis the moment I took delivery. So, I went ahead and covered the difference. I am not exaggerating when I say Amazon dropped it on my porch so quick I thought there had been a mistake!
The moment I held it in my hand it was over! I sat down, filled the cartridge with Lady Shikibu and wrote. I ordered the second Metal Falcon just days later...
Yeah, the metal falcon is on my to buy list. The resin falcon just doesn't hold enough ink(and I'll be damned if I use it as an eyedropper). The soft fine nib is outstanding, but I'm still considering the spencarian mod. Just don't know if I'll be able to handle that as a daily writer.
