I wasn't quite satisfied with the templates available, so i made my own based on iA's Helvetica template. Might add some more in the future.
Modern Sans Template, uses the popular Lato for Body and ZillaSlab for Headings.
This one features PTSans and PTSerif, which are incredibly easy to read. I scaled up the font-size to 13.5pt and line-height to 1.9 for even better readability after printing.
Try this if you prefer printing things out and reading from paper. Should also work fine when giving speeches etc.
