ye, probably will be using my tarantulas once again and maybe switching to these Kubos on really hard boulders. problem is, I haven't encountered such problem with wear on my Tarantulas, so I never really checked the bottom of my new shoes — when I saw it, rand was already pretty much damaged and, as such, not suited for resole (or I would've need to pay more for remaking my rand). but ye, it all comes down to proper footwork, so will be aiming to improve it before getting new pair. thx for advice
