96 1" studs up the middles is what i run. I bought the sled with a fried track two years ago and bought a 3/4 one and studded it. In heindsight I wish I would have gone with a deeper lug track as the 3/4 lug is really pathetic on anything other than hardpack trails. Studding it will only help you in these conditions, so if this is what you want then go for it, but if you want better traction across the entire range then forget it. I should have bought a deeper lug with the built in studs instead of what I got, but live and learn I guess. Hope this helps.
