Neovibe capacitor substitution question

[BubbaKahuna]

OK, another question about my impending Neovibe build. 

Do all those electrolytic caps have to be electrolytic caps?
Can other types (non polarized) be used in their place?
I have a ton of poly, ceramic and other types, almost enough to build one unless all those electrolytics shouldn't be other types.
If other types can be used, any types better than others?

Cheers,

Never mind - surfed the board a little more and found my answer.
