That's what I'm running as well, both tires and gearing. Which Hybrid are you running? I'm running the Gummy BFM. I wasn't sure what to expect but I'm a fan. I just spent four days in Death Valley and was impressed in everything- deep loose sand, serious rocks of every kind, dirt, gravel. Compared to the D606 it did slide out more quickly but as you say, once I got used to it it was predictable and actually a lot of fun.
Cheers.
