hi i have a quick question. i have 6 GOLD TIP HUNTER EXPEDITION 3555 Carbon Arrows with 2" blazer vanes. i will use those for hunting only. i plan on buying 6 more GOLD TIP HUNTER EXPEDITION 3555 Carbon Arrows but with 4" vanes for target shooting only. both are 7.4 gpi the only difference is they are 4" not 2" vanes. will there be any major difference in the arrows performance from the 2" to the 4"? i just want to shoot a arrow on the range that will fly just like my hunting arrows will.

*i understand i need to match my field tip weight to my broad heads weight, i'm only talking about the shaft and vanes.

*i know i could just buy 2" vanes but i have a chance to buy the 4" ones a bit cheaper.

thanks guys.
