Yaeah, what he said- You gotta learn to be friends with your front brakes. There's no substitute for it and it kills me how often I hear folks complaining about squirrely front brakes on their bikes on the motorized bicycle forums. There's no reason on Earth not to run/use front brakes to their full potential. I too have incurred front wheel skidding with excessive braking but indeed the brake input by me WAS excessive the very few times this has ever happened.
Look as long as you want, outside of patently unsafe Chopper motorcycle builds (which sometimes eschew front brakes for the sake of aesthetics), you won't fine one single example of an automobile or motorcycle that doesn't run front brakes. Maybe there's a reason for that..
Nevertheless, now that I've bashed you- I do think you're an ingenious mechanic. Now use all those brains to hook up a sweet front brake. BTW- you'll never have a lockup issue with a front drum brake.
