RE: Arrow Speed Question
OHM,
That is one of your options. You could also look at trying one of the heavier weight ICS carbons on the market. Some of them weigh as much as the average aluminum but still offer many of the benefits of a carbon arrow. You could also try installing those weight tubes that slide inside the Internal Component Carbons or, if you are into the homemade recipes, some weed eater line.
Hope this helps.
