I’d never imagine a conti as a replacement for a Panaracer. Contis very round and racey, Panas square and shouldery. XCPros start digging in when Contis have already let go was my experience here in South/Mid Wales. Some like the progressive nature of Contis as you lean them over, but they’re not like an XCPro.
I have Jones ACX on the front as a Panaracer replacement, but find them draggier than XCPro on the rear, so I’m using near-slick XCPros on the back. I don’t think the rear tyre is anything like as important as the front, I tend to use old, part-worns on the back. Last year I used a French supermarket tyre on the back; I skipped it in October but for 8 Euros it did me fine.
