Just stick it out and you'll get used to it. I used to go back and forth because I always felt like I skated better in vulcs, but I recently took the plunge and committed and now it feels totally normal.
Idk about club c's, but I've found different cupsoles are way grippier than others. The busenitz I'm skating now aren't very, but I also have some old dunks that feel super grippy.
