Non-flanged bars are far more secure when using NATO strap so I would stick with those.
While unlikely it is possible to catch the watch head and flick open both spring bars together using the flanged type.
Just about to reorder a nato strap for my Seiko Arnie. Previously when I had one, using straight spring bars (with a tight gap). There used to be clicking sound sometimes. Does this mean curved spring bars needed?
Thanks Brad

Clicking probably due to spring bar end moving in the lug 'ole. Some SBs can have a thinner end than others or could be due to wear. Some experimental R & D should fix.
