For "shatter" N-butane Or Iso-butane?

I have gotten so much contradictory info on the best hydrocarbon solvent or mixture for best "shatter" results. I have had the best luck with N-butane vs the iso/N/propane mix i used last time. Another member told me to go iso-butane. Curious what the community thinks about this matter.
