I hope Kenda doesn't mind me posting this but this is an email from them describing the differences between three of their tires with similiar applications; The Telonix, The Excavator, and The Nevegal.
The Telonix will deliver the most braking and cornering grip of the 3 tires you mentioned. The only downside is it's a bit on the heavy side. If traction is what you need though the Telonix has it in folds. It's a sleeper in the Kenda line that gets overshadowed by the Nevegal.
The Excavator and the Nevegal both deliver similar performance when cornering and braking are concerned. The difference being:
Excavator - side knobs hook up early and often when cornering and deliver a "riding on rails feeling". This tire is not easy to drift into corners making it great until pushed past its limits. Eric Carter designed this tire to be sipped on certain Knobs so if your into cutting rubber then the sky is the limit with this tread.
Nevegal - the side knobs hook up consistently throughout most corners making this tire a more predictable drifter than the Excavator. When it breaks loose it tends to be a little easier to handle but it delivers a little less of the "riding on rails" kind of feeling. This tire has become a Legend for a reason though. It can definitely hold up to aggressive riding.
