Nicked my strop. Diamond Spray or Crox paste on Leather?

[jcsixx]

Well, I got careless and nicked my strop while stropping my razor while simultaneously trying to check out my shave in the mirror. It's still usable, but I'm just going to buy a new one. What do you guys recommend for leather...paste or diamond spray?

I know personally preference is usually the standard response, but what do you recommend? I'm assuming diamond spray is easier to apply...because it's a spray.

Just looking for opinions. I haven't really used pastes or sprays to this point.

So just lets consider this a poll.

Diamond or paste? Which micron?
