The cabelas stalker extreme carbon arrows are .003 straightness and +/- 2 grains, you can get a 6 pack fletched with 4" feather for about $50... They are made by Easton and are great arrows, tough, accurate and cheap. They should fly pretty good for you with just standard inserts. For target you really don't want a heavy arrow, about 8 gpp is perfect because it gives you a nice flat trajectory for unmarked yardages. Those arrows are also great for hunting, I have used them for years. I suggest the 400 spine, fit the nock to the string and tune from there, should be pretty simple. Fyi they are basically the same arrow as the Beeman ICS bowhunters.
