I've tried two different kinds of rings on RealForce RGB boards. First I transplanted the rings that came on my Noppoo EC108Pro. Second I installed Hypersphere rings. There is definitely more tactility in the first case compared to the second.
So, any rings that come from Chinese sources (like Noppoo, Royal Kludge, or Plum boards) and Aliexpress will provide the most tactility. Hypersphere rings will reduce tactility a bit but still leave enough of it that the switches don't feel like linears. However, given the thickness of even the lightest dental bands (2.5oz), I expect they would reduce tactility almost to the point of linearity. But I won't know for sure until I try them myself.
