I have the KTS, K-10s, Hillsound Trail, and Hillsound Cypress 6. My favorite of those is the Cypress 6. Quick on/off. Clamp down super tight so they don't "walk" around the side of your boot while doing a lot of side hilling and the "anti-snowball" pad seems to keep snow from building up much better than the others IMO which allow the crampons to still have contact with the ground for traction rather than walking on snowballs under your boots.
