At low rank, don't bother. You can even get through high rank with low rank armour if you wanted to.
If you really wanted to, you could, but it's a little tough for some people. I've found Rathalos armor to be pretty good if you get rid of Recovery Level -1. But I'd recommend that you just wait til high rank to make a new armor set, especially since you need a plate to get the armor. Those take FOREVER to get if you're not lucky (like me!)
