Best application to read a file?

[Guest cybercamel]

Here's the thing, I've got a 4mb pdf file I'd like to put on my C500, and I'd like some advice on the best way to do this. I do have ClearVue installed, so it wouldn't be a problem. I was wondering though, whether it might be better to convert the file and use MobiPocket. Would this make it an easier format to read or are there any better methods?

Any help appreciated, cheers!
