You can only rengineer the wheel so many times before you screw it up. i have two vex's . an fl 18 and an fl8se and i think vex got it right as the only time i have a problem is when someone with a marcum fishes too close to me. how much power do you really need in a flasher when you rarely fish in less than 75 ft of water. both my vex's have plenty of power for that. plus vexilar has been around for a long time and probably will stay around a long time. who knows about marcum???
