If you are completly new to the game, and you do plan on hunting this fall I would just stick with the bow that you intend to use. If you want one for big game and a lighter pull for small game/bird, then work with your big game bow often until you are completely comfortable with it. then work in the lighter one, also will help to break up the monotony of working with one bow. If you feel your self starting to break form, or doing something wrong, stop, put the bow down and walk away for a few hours.....or days, there is nothing worse than starting a bad habit now, then trying to break of it later.
