i was thinking the very same thing the other day! when i was a kid,it was always 3lb mainline and 20/22 hooks.that caught us everything from bleak up to some nice perch and bream. nowadays my lowest mainline is 4lb but it's 6 that i use mostly and size 12/14/16 hooks!
Gone are the days when i'd sit it out for a few tiny silvers on micro hooks, maybe when I was younger and fished every single possible moment. But I figure if I have to fish that fine then it aint going to be that enjoyable fishing anyway, I walk the bank insted or turn to pike fishing. I remember size 26's with a few ounce bottoms and having to play in 1 to 2oz silvers....
Still got plenty size 24 and 26 in my box but not use them for years[:I]The very last time I use a size24 and no.2 elastic was in Roses' match last May[:0]These days,size 20 is the smallest I use in winter.
I use 22 and 24 in the cold weather when scratching )
I still like fishing for bits on a freezing day with pinkies )
Got some 26's somewhere maybe I give bloodworm a go this winter !
Got down to 30 in eyed barbed for tying some American fly patterns but could never quite manage it!
