I’d like to hear your thoughts on the 1.6 cobra with igrip screw in studs. I would run the st-25r as it is suggested on their website. I had an ice cobra on an old renegade and it gave me just a bit of added confidence when things were crispy or there was a bare spot on the lake. I figured these would be a nice light option on my backcountry 600r. Also thinking I might be able to get away without tunnel protectors since the sled easily clears a 2” track. Thoughts?
