menaztricks,
>>Since your shafts are 27.25"
Is this measurement the length of the PSE Dominator 200 "shaft material only"? Or have you measured from "nock grove to point insert". SFA assumes "shaft material only". The difference in the two meaurement methods can be between .25" on .75" depending on nock type and whether or not you use a nock bushing. This seemingly small difference will have an effect on a shaft's dynamic spine and program output.
>>I noticed too, under the cam options, it says 1cam soft, 1cam medium, 1cam hard. What does that mean?
Cam type and degree of "hardness" is determined by the manufacturer IBO published velocities. A Bow/cam combo generating 291fps or more is considered a hard cam. A velocity of 261fps to 290fps is considered "medium". Anything 260fps or less is considered "soft". With an IBO rating of 295 for your bow, it's only 4fps away from to the dividing line of what is considered medium or hard.
>>the only way I got it to be right on the center, is if I pushed the synch button. Is that something I was supposed to do?
No. The "synch button" is for users that want to over-ride the program spine recommendations. What it does is "synch" your setup to the currently selected shaft. Say you have a shaft that you know is "perfect" for your setup and the program is suggesting something else. Clicking the "synch" button adjusts the program calculation so your selected shaft is perfect for your setup. As long as the "synch" button is enabled, subsequent database searches will be adjusted by the "synch"ed amount. This allows a user to find shafts that match the one that they are positive works for them.
>>the only way I got it to be right on the center...
One thing to be aware of is the filter check boxes for "Target", "Hunting", or "Both". The choice you make will have an effect on what spine the program recommends. This is an adaptation from the Easton selection charts. Easton publishes two shaft selection charts. One chart is used for selecting target shafts and the other for hunting shafts. Why two charts? Because for hunting applications, usually a broadhead is involved and it's easier to tune broadheads with a stiffer arrow. SFA and SS allows you to pick "hunting" or "target", but also give you the option to select "both". The "both" selection allows the user to split the difference between target and hunting shaft recommendations.
>>but according to PSEs chart...
One thing to remember about charts is that most are very general in nature. A particular manufacturer may only have 3 or 4 spine weights in a given shaft model and those 3 or 4 spine weights must cover the total spectrum of possible bow draw weights. An example of this is found on the selection chart on the link below...
http://www.huntersfriend.com/arrowhelp/carbon-force-arrows-chart.htm
Reading the chart vertically, a 28" 200 shaft is recommended for bows with draw weights from 40lbs to 63lbs. Reading the chart horizontally, bows with a peak weight of 52lbs-57lbs can use a 200 shaft with a length between 26" and 30". Hhhhmmmmm. While the recommended shaft might work over these wide ranges, I suspect that the given shaft will work best at the chart boxes located in the center of each range.
Please don't take the above to be a flame of you personally...it's not, though you might think that from my writing style.
It seems as though most of your questions might have already been addressed. If you have additional ones that weren't covered in the above posts feel free to post more here, e-mail me (links are in the program), or phone (# and office hours on the website).
Appologies for the "novela length" response...
