Get the Samick in both sets of limbs. It will be fine for both hunting and practice,though I personally might go 40-45 lb limbs and just shoot the one set.
When you shoot the Samick enough to get good with it, you will have a much better idea of what you want in a bow. You can kill with any bent stick and string if you can shoot. All the fundamentals are the same. A more expensive bow is for later when you know the exact reasons you want a particular bow.
