Glad you're enjoying the links!
I just finished one run of friuls the other night (about 1/3 done with the other), and ended up using I think 95 links.

Added two links back - so a total of 95, I believe - and got about the degree of sag I was going for:
On the Bench: 1/32 Trumpeter P-47 | 1/32 Hasegawa Bf 109G | 1/144 Eduard MiG-21MF x2
On Deck: 1/350 HMS Dreadnought
