I'm running a Baldwin F/S and Donaldson F/F at Air Dog and a Cat 1R-0749 under the hood. I keep 2 of each in my toolbox on the truck and 3-4 more sets at home in FL. I also keep 1 extra set at my apartment in VA. Just in case. No issues with any of them to date. Knock on wood as I'll be driving to FL in 3 days.
