Chroma Caps vs S2 standard knobs

So here's my dilemma.

I'm going to be ordering an S2 on Monday from DJTT. Now I really like the look of the S2 with black knobs the most, so I was thinking about just getting the black chroma caps. But then I got to thinking; maybe I should get the white/grey ones just in case I ever wanna change.

So ultimately here's my question, how much better (if at all) are the chroma caps compared to the standard S2 knobs?

quite abit better IMO. except for use on the xfader, the chroma ones are too gummy and sticky

So would you recommend using them on everything but the xfader?

I strongly recomend them on your S2, (x-fader is personal, i love it) especially on your (gain) filter knobs!
