how interesting. I tried running both badlands and bowties in my rustler...on clay.
Motor and ESC temps here definitely higher with the badlands on. The runtime was down as well.
I would think the same logic would apply on tall grass. (3-4 inches? Good Lord, man...where is your mower?

)
I will say one thing, though:
Run badlands if you're on a budget and can't afford to keep on replacing tires. Those buggers don't wear for crap.

Ran them for a month, think I saw the knobbies go down about 2mm. Geez...
