    You could figure out fps by using a chronograph, but if you don't have access to one, alot of guys on here say the calculator at http://www.backcountrybowhunting.com/articles/calc/ seems to be pretty close. Good luck, keep us posted.

    When I ran your specs the calculator showed me only 301 fps and 73 ft. lb. of kinetic energy, which is excellent, but not the speed you stated. I don't know what your arrows weigh, but I used the lightest weight the calculator told me for your setup.

    Working up the arrow on GT's website it comes up to 420 grains. That's figuring a 28" shaft, 2" Blazers, acculite nock. Plugging the numbers into Backcountry calculator and using 317 fps for IBO speed, 20 grains on the string it calculates a speed of 281 fps with 74 lbs.ft of energy.

    This would probably be the maximum speed your bow will achieve if it's tuned very finely. Real world? I'd subtract some more and estimate that it's more like about 270 fps.

    A lot of people over estimate things. I've had a lot of people say my arrows are zipping along at 300 fps when in reality they were only dong around 250 to 260. So much for eyeballs.

    If you have a dicks sporting goods around you can put a few arrows through there chronograph and find out what speed you are doing. They don't charge much to do that. As far as strings many different makers but try H&M strings or go to archerytalk and look at the string builders on there.

    One thing to remember all your specs need to be right to get the most out of a bow. The ATA, BH, Cam position, Draw length. With all this correct the bow will preform well.
