I have Cabela' s Stalker Extreme arrows and need to change the vanes on some of the arrows as they have been worn. How much of a difference does it make if I cannot match the new vanes with the older vanes. I believe the old vanes are AAE elite platifletch. I have some Bohning 4" vanes. The AAE' s are 3 7/8" vanes. Please advise. Thanks
