i use cool blue and have had good luck EXCEPT in some of the bag targets or some indoor target face material. my easton inserts are slightly, just slighly, larger than the shaft. that seems to catch on the face of the targets.
i used it on some victorys using their points (no inserts) and didn't have a problem. i do have problems if i don't do a good job of cleaning the dust out of the shaft using soapy water followed (after they dry) by 91% alky. cleaning the inside of the shaft is critical imho.
