350 is the rating of the spine of your arrow. You have to find out the gpi(grains per inch) or your arrow, then measure the arrow and calculate it. And then account for your fletching/insert/point/nock weight as well to get an overall weight.
Your arrow is weighted at 8.9gpi(what I found on the web anyway) so...
do 8.9Xarrow length(which is measured from the nock throat to the end of the shaft, nock throat being the deepest part of the v in your nock). Then add a roughly estimated 25gr. for fletchings, nock and insert. Just a rough estimate there, but that should get you relatively close
Oh... and then add your fp weight after that.
hope that clears the whole arrow thing up a wee bit. There is tons on it on the web. Try and read up about arrow spine.
