RE: Gold tip vs CX
If money was not an object, yes something along that lines. It's just that the two arrows you listed are sort of average bargain carbon arrows. If money was not a concern I would look at the more expensive better carbons by either company. They would probably be pretty equal, just depends on which brand you like better.
In the price range you listed I would probably shoot bemans or nitro stingers instead of the other two. However for the money I would just stick with aluminums. That is personal thing with me though.
From what I have seen and heard, me personally between those two I would pick Carbon Express over Gold Tip. The GT's seem to be really popular, but I don't always hear good things about them. I have never shot them though so it is really not my place to bad mouth them. They can't be all crap or they wouldn't sell as many as they do.
