I went through a similar dilemma did a lot of research and ordered TA 2s to be fitted at the 6000 mile service, just before our first trip to the Picos. On the day of the service the supplier failed to deliver and so for that at various other reasons I went with Tourance Nexts as they were the only tyre in stock, I was told that they were being fitted to tour company bikes. So far I have done nearly 3000 miles on them and are still pleased with them. The rear is showing signs of squaring off, but performance seems unaffected. I never go off road, but equally don't want to feel I could ride round a gravel car park. I had PR4s on previous bikes and suffered from punctures, maybe unlucky but it seems to be a regular occurrence with them.
