I've only managed to damage the feed in one of my 7 or 8 penBBS models and I was very harsh on it. I routinely remove them all.
The feeds are not what I'd call a weak point as long as you don't abuse it.
I have inked both of my 456's and both had very dry, boring nibs. I swapped one for an ultra extra fine custom ground steel nib, and the other I just opened up the original nib and it's now a nice wet medium.
Fit and finish are superb. Easily worth every penny they ask and then some
