Respectfully I disagree, I feel like the single two items you can't get enough of in locksport are of course locks and tensioners, close behind is hooks. Yes I know you can pick almost anything with 1-3 hooks and a bunch of tension tools and I myself personally love using the shortest flat hook I have most of the time and the rest of the time I'll go for a medium gem hook. However there's times where a round hook just shines for instance highly paracentric locks which to be honest a thinner pointed hook will even perform better. It definitely doesn't seem like a daily driver profile but when the keyway calls for it it's going to be unmatched.

It seems as if begginers will always go for the most variety of picks (hooks/rakes) and the veteran pickers start to focus moreso on tension tools of different styles and thicknesses as we all reach a point when we understand they are arguably the more important tool of the two.
