I haven't engaged the gearbox on my South Bend Heavy 10L in over 10 years. My ELS does all the Z axis motion including metric/imperial threading and is especially handy for boring into a blind hole. Yes, I still have to look at the X axis dial and if I want tapers then I engage the South Bend taper attachment.
Backlash on that old lathe isn't an issue for Z since the cutting is always in one direction although there is a backlash parameter that can be set. Backlash on cross slide is a bigger issue for parting off.
