TETRIX All Terrain vs. Stealth Wheels vs. ???

[GeeTwo]

I'm not specifically familiar with these wheels (and the web site comes up with an "Oops!" page for me), but you should check the wheels for wear and contamination (e.g. oil or dust). I have had trouble at FRC and smaller-than-FLL scales with tires that got dirty and lost traction. Cleaning the tires has also helped at least one FLL team whose programs would not perform at competition like they did at the home field, due to dust on the wheels (the girls looked at me like I was out of my mind when I suggested it, but about an hour later, I got a hearty thank you). It is also possible that the churros' surface is contaminated, but if that's your problem, you're likely to be faced with it at competition without such a simple solution.

Yes, I see them now. I am wondering if those wheels might be better for climbing the grade on a bias than going straight up.

Finally, while I haven't seen the FTC rules, and perhaps they disallow it, has anyone considered engaging the churros on the steep grade with hooks or grippers and climbing rather than (or in addition to) trying to roll up them?
