The best place in the country for uplift imo is south wales and adjacent. BPW obviously but also Dirt Farm and forest of dean, flyup 417 for a more trailcentry uplift. For me it’s harder to figure out non-uplift around there (there’s lots of great riding but it’s become increasingly secret) but that’s OK,we end up on full on uplift holidays anyway.
tweed valley’s an obvious alternative- only the one uplift (*) but all the pedalled riding you can eat. Can be downright overwhelming with choice. TBH innerleithen dh is a bit of weird, oldschool experience at this point, little useful waymarking and it’s super confusing to ride until you’ve spent a bunch of time there. But as long as you’re going “I will ride a random trail” and not stressing out if you’re on the exact right line that’s fine. It’s definitely possible to accidentally end up on something much harder than you expected though.
(*well there is the glentress uplift but it’s not for you)
