Anybody tried any other feeds in the 699?
Mine wasn't writing well, so I used my Swiss Army to enlarge the feed slit, then dug out a 316 nib left over from a swap. It's better, but I had to bend the nib by pressing on the reverse side to try and get it to better conform to the feed in order to get decent flow (there was a huge gap) and it just looks odd.
Pilot feeds from both a 742 and 912 both FA nibs plus the ebonite feed from felxible nib warehouse both the 2 and 3 channel versions. In both cases a #10 Pilot FA nib. The FPR ultra flex does not fit nor will the Conklin flex however using the conklin feed you can kind of shoehorn the nib in there but in messing with it I broke a section. Good thing it was a spare. I have my FA in my daily writer 699. What I want now is to see if a TWSBI section fits it and if so swap in a Conklin flex and then awesome. The FA obviously flexes better but that Conklin in rose gold just looks beautiful. The threads from a FPR Himalaya fit but the back end sticks out too far.
