Don`t you think your tender behind would feel the vibration if thered be any? I can assist the voiced opinion that the unbalanced wheel pants play an important role in the shimmy drama: So far I have made high speed taxi tests with my D-ELIY up to 55kts on the runway, no wheel pants installed so far, and observed absolutely no shimmy, neither empty nor fully loaded with wife Uli and full tanks. BTW I hope to get my german Permit To Fly in July. Or so.
