Redneck,
Here is the link where you can download the demo and then decide to buy. You only need the SS (Shaft Selector Software). However, the SFA (Software for Archers) has the shaft selector as well as other features. When selecting the shafts make sure to choose the Hunting choice on the left side instead of the Target. The hunting will give you the stiffer shaft. Also, if you can go shoot any arrow you have now and get it chronographed and the arrow weighed. With that info and your bow info you cna set the software up for your bow and be a little more accurate in shaft selection.
Archer's Advantage is also a good program that allows you to install on more than 1 pc. You can buy a CD with the Ontarget2 software and 3 user rights for $50 at Lancaster Archery.
