Jordan - you got a "topping saw" - every tool has a purpose. Your using a tack hammer and you want a framing hammer. Wait until your trying to lift a mid sized saw to chest height for a bunch of hinge cuts - then you will love that little saw you have.
Use the selection guides they list and you will be fine. If your worried about not having enough saw - go a size bigger than you think. I think mine is an MS250 and it suits my needs just fine - gets a little heavy on repetitive light work, and sin't going to cut down any monster trees either, but it's a nice medium in between for what I need. Right tool for the right job.
