actually, mx reds are somewhat the opposite - rubber domes 'collapse' in on themselves which increases resistance then when it passes a certain actuation point, it 'slams' down onto the membrane. in other words, sudden increase then decrease in resistance is another way of saying tactile. basically rubber domes are tactile (bump feeling) and reds are linear (smooth) . if you are referring to actuation, i compared cherry blues to a rubber dome, and it takes 7 £1 coins to actuate both. cherry mx reds use 45g springs so will take less force to actuate compared to cherry mx blues which take 50g of force to actuate. so no, mx reds are very different to rubber domes in feeling.
(hope that made sense xD)
