RE: arrow straightness
Oh yeah, and I agree with everyone about spending more money on good shafts and take a few dollars away from say the sight, quiver or stabilizer. When peopel ask me what arrows they should get, I tell them this....
But the absolute best you can afford. Think about it. That arrow is the delivery system to your payload, the broadhead. Don't skimp on arrows, skimp a little on a sight or stabilizer. I also tell them to not skimp on rests and strings. These three, are the most important aspects to your bow/arrow system.
