Country - questions like this always baffle me. I don't want this to come off the wrong way, but why would you want a lesser quality arrow for practice and use your 'better' arrows for hunting. My advice is to buy yourself another 1/2 doz of the arrows you are using now and keep them aside for hunting and use your older ones for practice - provided they are in good condition.
Remember practice is to make you a better shot. Shooting a lesser quality arrow is IMO defeating the purpose.
