Given the coice,would you prefer top of top tube or bottom of top tube cable routing and why? Im trying to decide for my next frame.I think under looks neater but im thinking on top is more practical.So cant make me mind up.Ta.

I've had every possible combination and can honestly say I don't really care.

Depends if you're going to lug your bike over your shoulder. If so then top routed might be better.

No shouldering here.Such trivial things i worry about but i need to make a decision.Im thinking top,no bottom,no top.and round and round i go…

Continuous or not? If not, I guess top would be more out of the mud?

Yes continuous,its on a hardtail frame.Good point about the mud.
