Crew chiefs on Tony Shoe's, Massie's, Antron's, Capps, Hagan's, Beckman's, Gray's, both Al Anabi, Cruz, Terry McMillin, Both Wilkerson's all agree. Firecore50 wires are lasting more than 25% longer than previously used wires. Same with the ProMod teams. Less RF noise as well. That is coming from their feedback.
After hitting the newbie thread, do a search on here for Firecore50. Glad to help when you are ready.
