I have switched to terreno wets over PDXs. I’m very happy with them. Interestingly on sunday I raced with two bikes, one with PDXs on and one with Terreno Wets. I couldn’t really tell the difference in terms of grip; but the PDX seemed to ball up a bit more.
edit. my tyre thoughts are that once the ground has got squidgy, if the course is all grass/mud you arent going to notice any rolling difference between intermediates and muds. Where I used to find the PDX poor was on hard surfaces, there was a vague moment between being up straight and fully on the edge knobs whcih i didnt like, especially if a bit of gravel dust as well. I’ve not had the terreno wets on hard surfaces yet but i am hoping the more even spaced transition knobs mean that wont be an issue
