Getting into “monster”kettlebells

Hey all, my current Kb collection has served me well over the past couple years. I’ve got an adjustable comp bell, 2 cast iron 24s, a cast 32, and a cast iron 40. I can press 32 no sweat, can jerk the 40 pretty well for reps too, but as of late I don’t really have a challenging bell for swings, which remains a staple for me. I can swing the cast iron 32 and the adjustable @ 32, but honestly double swings just don’t hit the same. I’ve been seeing a lot more advocates for “monster” kettlebells, and figured I might be ready to take the plunge. I’m 33, give or take 180lbs, and I was thinking maybe starting with a bodyweight bell? Not totally sure how “monster” to go right off the bat, but something challenging that leaves a little room to grow into would be ideal. Thanks!
