Actually, if you understand the math, it's okay if your angles are not perfect, as it's fairly easy to fix in code. The ease of climbing ramps is determined by the type of omni wheel you buy. Unfortunately, most of the off the shelf omni wheels our team found had lousy traction, although it would be possible (mabye not feasible?) to manufacture your own.
