I'm not saying the paths are perfect, but then, what roads are either? There is an annoying bit between Bowling and Clydebank which is towpath gravel (if it was down to me I'd upgrade it to tarmac like the rest), but certainly with the rest of it, there are miles on end of tarmac path which are just as good as the road through being.... tarmac, and there are few pot holes, etc, and more of it wouldn't go amiss, like the Dutch model!
