Hey, for anyone that's used all types, how does the rolling resistance between the normal V wheel vs. the mini V wheel. vs the Xtreme V wheel compare? Do you find that rolling resistance is different when using V-Slot vs. Open rail? My application involves very light loads, but at higher accelerations at a higher frequency than is typical. Positional accuracy is less important than the motion profile. Anyone with any experience on these matters would be greatly appreciated.
