RE: competition/hunting bow?
I know a lot of target shooters both 3-D and indoor that use cammo pattern hunting bows. They say they are easy to re-sell when they want something different. And target colors cost more to begin with. Model for model they don't shoot any different.
However it really depends on what you want to do with it and how well you shoot. I don't know that I would suggest a 30 inch ATA sub 3lb bow for serious target work. It could be done, but they are not as forgiving as a longer heavier bow.
