Just a thought on this reducing tube length by 1mm or so, make sure it is only 1mm and not in danger of leaving the clip end rubbing on the belt or sticking out past it.
Some of the crap kits we use have little room for errors, also in the case of FP you could crush the nib or not seat the cap correctly by taking it down too much init?
Definitely agree with you on that score though. You can't be wrong all the time.
