RE: Would this be adequate?
Who really cares about where that bow falls into the spectrum of low end or high end. If you become proficient enough with it to execute the shot that you need to make, nothing else matters.
If you are beginner, find someone in your area....go to your local pro shop and find someone that will mentor you. Listening to someone who may have been around the block once or twice will help dramatically. Learn, listen and practice...practice...practice!
Good luck!
