Ive had a good look at my O.S map above Largs ..lots of decent sized hills but very little in the way of marked trails ..( I can see now how you got your 4000ft of climbing ! )..have you got any routes you can share?Aye, it was revived a few years ago, but has disappeared again, sadly. Some great riding up on the moors though.
It could well be worth a look as day 1 of a trip up North being only 3hrs away ..
