Background Info: I shoot skateboarding and biking, often indoors and at night, and I am working with a Canon camera, PocketWizards, and off camera, wireless flashes.
Situation: I am selling my Speedlite 550ex because it does not work right with my PocketWizards (I also tested a Speedlite 420 and I found the same problem) so I am trying to steer away from the Speedlite family. Any recommendations for what flashes I should look in to for shooting sports (I am trying to stay $300 or under if possible)? Any advice would be greatly appreciated! -Justin
