On the DRZ I find the 'Deathwings' to be very good 50/50 tires. I think they are poor in the mud and sand, but what 50/50 tire is good there? Also I don't trust them on the wet pavement but where I ride (dirt and gravel fire roads and some single track) I fing them to be pretty good.
wet is the problem - I commute on my bike every day and a fair bit of that is through the rain. never trusted them in the wet.
