You seem to be doing very well with the one you have, if you personally are questioning a new bow, shoot some of the new ones and see if you really feal that much of a difference. In my standards, you are doing so good with the bow you have that personally i would stick with it.

Unless you really feal a difference in a new bow, and feal like the bow will give you more potential to do better.

Otherwise, stick with the one you got.
