but was just wondering if it's worth keeping those over the stock PB Tools levers in my bag?
If you get this tool, recommend it highly, you could always use them at home changing tires to see how they perform, then make the decision. Full disclosure, on one bike, my old Pinarello, with Campy rims, I still use my old trusty VAR tire tool and carry it in the bag also. All other bikes have one of these in the saddle bag.
