Every low profile reel ihave holds between 120 and 150 yards 12# test for 3 reasons:
I have had a fish in the Chehalis run me across the river and brought it back.
I thumb the spool so a nice full spool even when I have 50 yards out is a must.
If I lose 20 yards from a couple break off I can still fish without worry of being spooled.

I can't help with larger line, only time I go with heavier line is for sturgeon and Ling cod and then I am using high capacity round Penn reels.

If I could afford a larger capacity reel and I liked it I would get it. Salt water fishing eats line fast and respooling on the jetty is not fun. Not to mention hooking a nice skate or ling cod on light gear and having them run for the deepest hole they can find. Someday i will get me some 200 yard 12# capacity reels and never have to worry about it.
