Resole Rubber for Evolv Shaman?

I'm getting my Evolv Shaman's repaired and I have three options for rubber:
Stealth C4
Stealth Onyx
Vibram Grip

I'm generally happy with the Evolv rubber but it is not available. Which of the three choices is most similar to the original rubber?

Or is this an opportunity to put something better on there?

c4

X2 for C4.

I used Yosemite bum for my evolv shamans and they came back like new.

+1 for yosemite bum, they did a great job for me too

Thanks for all the replies. They are already at the local shop so I can't send them somewhere else, that's why there are only the three choices. I'll report back with my decision and how it turns out.
