I think both sound great!
The template challenge could be used by both paper and digi scrappers (the paper can "lift" the idea onto their pages). Speed Scrap would be technically more difficult for paper scrappers though, I would imagine. (although, I think I did do some paper layouts in an hour or so. As long as the directions kept paper scrappers in mind, it should work for them too).
EX: Nothing toooo hard for paper. Shapes ok, strips, ribbon, buttons, doodles ok.Number of photos and papers ok. Glitter (can you do glitter in paper scrapping wihtin an hour?) alphas and fonts would be ok.
Just trying to play fairly here!
