Some more background. On my litespeed 5g I run GP5000 32 from road to light gravel. I have been using them for bikepacking too and that's a bit too much for them. I also have a set of wtb resolute 650x42. I really not too stoked on them. A lot pressure they are a drag. At high pressure they roll ok but what's the point? So I am looking for something between the resolutes and gp5000 mostly for bikepacking and rougher rides. Those Rene Herse look good but they are too much $$ for bikepacking.
Panaracer gravel king seem to roll well, they are cheap and come in many sizes. The 40 measures 37 on
