ooh yeah, that's the good stuff
at the risk of going full tire nerd and leaning into confirmation bias, your impressions make a lot of sense
i found the previous butcher grids to brake well in a straight line and wear slowly (glad those two characteristics remain) and corner really well in most conditions, but get sketchy when things get especially wet or dry. it sounds like the new rubber has solved the former issue; as for the latter...
there's an interesting primer on mtb tires on blister that talks about the impact of transition knobs. if the butcher was redesigned so that there's less of a gap between the inner and side knobs, that might explain why they don't dig in well when leaned over in hard conditions
thanks for indulging me pete ;-)
