Read the entire post. Note that I said "GDC allows" and "again". And know your FRC rules history. Slip rings are an on-again, off-again legal part. (190 had custom ones in 2008 that were legal--there wasn't a prohibition on custom ones then. COTS ones were not legal at that time, IIRC.) COTS ones even more so. This is one of the few times that I remember COTS slip rings being legal for competition use.

And note that the rules change every year.

So, IF the GDC chooses to allow slip rings again, then you don't have to worry about motor wires twisting. Otherwise, you do.
