Tights

This is a bit of a worry for me. I carry most of my shortness in my femurs. I shall look into thermal bibs some more, before committing. Either way I can see myself covering my knees up all year. I think my cold weather running has aged them beyond their already advanced years.

Cheers for the advice.

I think you're overthinking it. Even if they're not exactly the right length etc, I still find tights more comfortable than knee warmers.

My knees are definitely happier when covered. I have on occasion (really really cold) recently worn knee warmers under bibs for a bit of extra warmth - start to move around after a while though. Wish I could spring for better quality tights.
