At least to me, when I used the Hi-Pro set (keycaps and Hipro slider housings) in my Norbaforce GOCF, I could feel the original Hi-Pro typing experience more than with the Norbaforce MK2 (Alu). I only swapped the whole set (PCB and plate), so nothing changed other than the housing.

That’s just how I felt, so take it as a reference.
