I have lots of kettlebells.
53#
44#
35#
2-25#
2-18#
2-14#
2-10#
I use the 53# and 44# for swings. The 25# and 18# for double armed moves and farmer's walk, racked walks and overhead walks. I use 14# and 10# for 1-armed sit ups (mostly). I have friends that come over and use the lighter ones as well.
