>>Those of you who have tried both the 3776 and any of the Pilots, what are your impressions? Pros, cons?
I have a Pilot Custom 92 demonstrator, Custom 74, and a couple Platinum 3776s. The Platinum nibs are the smoother, but I'd say the Pilots are more springy. Can't go wrong with either nibs. My pick of the bunch would be the Custom 92. It does such an incredible job displaying the ink you put in it. https://www.instagram.com/p/9w6RqeSyzk
>>I prefer the design of the CH91 and CH92. I'm not a big fan of the cigar shape, but it's not a deal braker.
Give the cigar a chance, I didn't like it at first either, but now the 74 and the 3776s, well I just LOVE the shape and prefer it to flat topped pens like the Sailor ProGear. I find it more elegant.
>>I know the CH92 is a demonstrator with piston filler, which makes it slightly more expensive than the others. Is it worth the money or is any of the other a better buy?
For me it is, see the above photo. I love my 92, and if I could only have one, that would be it. Then probably the 3776.
