just bare shaft tested three shafts with my 35 lb. Greatree Deerslayer and 35# black max limbs on 19" and 15" Morrison ILF riser. Predator 11 600 and Carbon Express Cheeta 3d. 650.  Victory V1 600. They all flew fine. Trimmed to 28-1/2". Fletched them with 5" parabolic RW helical fletch and 100 grain field tips. All three arrows fly to same spot on target with all three of these bows.  Bows are all center cut window bows so no crawling of arrow around the riser.  One bare shaft cost $4.50 each One $12.00 each. One $9.00 each.  An eye opener experiment on my part.
