RE: 3D/indoor Arrow Help Anyone?
The Easton Fatboy shafts would also be good "linecutter" arrows. You want a 200/250 in the CE shafts, or a 400 series Easton shaft. At 28 or 29 inches, 60 lb. draw, and with a 100 grain tip; the 400 series shafts will spine out just about perfect. 340's and 350's are going to be too stiff - unless you want to run a 31" shaft and possibly go with a 125 grain tip.
