I've been riding heats lately as well, and they've only been lasting a few months. so i'm also looking for a new brand.
I'm thinking about getting some senates cuz they're cheap from pretty much any rollin website. but i here 4x4's are the shit! so i might try those.
i have been riding the eulogy lievanos wheels (58/90) for about two years now.. (not just one set, multiple sets) but they are the longest lasting and smoothest wheels ive ever ridden.
big and perfect hardness.
never chunk.. never explode... can ride them almost down to the core.
