grooving slash tire which nobs to cut, these or those?

Not to shabby! I'm sure you could feel the difference since the stock treads are so horrible to begin with. I tried cutting my tires too, but the rubber compound is just too hard so I didn't notice a difference. I picked up a set of the NewEra 17mm adapters and 1/8 buggy MOABs. That solved my traction problem! As I understand you have to run the stock tires for racing which is something I hope they change.
