Adjustable, competition kettlebells are a thing now. You don't need to have just one weight and you can have the same, high quality, competition scale kettlebell at all weights with just one. Kettlebell kings has a model and there's a couple others out there.
I would submit that a Gun Nut competes with the most radically modified, bespoke, hot mess of high speed low drag they can to shave 100ths of a second off their mediocre times because they claim gear makes you better and if you don’t run their gear you suck while Gun Nerds take a 1930s vintage Model 10 to Bianchi Cup and smokes the competition just to see if it can be done.
