I admit I had a look at possible routes for these two (got more into Grahams since buying Mr Dempster's guide) and decided it was too much hassle, too far and I couldn't be bothered
Knockfarrel Hill is my favourite sub2k, we often go for a stroll there when fresh snow arrives. It's a good place for mushroom picking, too. Shame that some of the old forest was cut down.
