IMO the old half step with its double shifting went out with 10 speeds that we had before the middle 80s. With the 8 and 9 speed rear clusters and more, shifting has taken on a whole new aspect. Most of us just look at triples with 8 or 9 speed rear clusters as ------------up hill, level, and down hill. After picking the proper front chainring for the road at hand, we then just shift across the rear cluster for slight variations in the road. We no longer need to be slaves to half step with its double shifting. Life is now simpler, dont complicate it if you dont have to.
