Which version/casing of each? Comparing my 27.5 2.5 non-WT DHs against my 27.5 2.5 WT DDs I don't see any obvious difference in the shape/height of the knobs; the noticeable difference is the width of the channel between the center and side-knobs.I fondled some 'normal' minion dhfs next to some WTs yesterday.
I'm changing my assessment. The knobs on the WT are wider/longer but not proportionally taller. They're just effectively shorter. So like, you know, same thing really.
